“I am half Basque,” Iriondo says. “And these words—like “mahai” and “metak”—come from the Basque language. A metak is when you take the grass that you’re cutting, and you make a mountain of this grass in the garden. In the past, you gave this metak to the cows.” Another traditional Basque practice and type of metak involves shredding and drying corn stalks to use as fodder over the long, cold winter months. So, a metak is a pile of collected things that are preserved for an extended period. In Iriondo’s view, this serves as an analogy for something deeper. “I love this idea, because you can put everything inside the metak,” he says. “It’s like a collection of your emotions. For example, with my shop, Sound Metak, I sold different kinds of things—from old gramophones and vinyl shellac records to fuzz pedals and jukeboxes and guitars and amplifiers—it was a lot of different things. Metak for me is an idea, and my instrument, the Mahai Metak, is the same thing. It’s an energy from my fantasy, which is everything I can put out from my mind.”

Conceptually, metak also helps to explain Iriondo’s musical diversity. Born in Milan, he started playing the guitar at 17, and became something of an Italian celebrity as part of the alternative band Afterhours, with whom he’s been a member since 1992 (except for hiatus throughout most of the aughts). But Afterhours is about as mainstream as Xabier gets. He’s also made incredible noise with myriad projects, like his recordings and performances with Can’s Damo Suzuki (Damo Suzuki’s Network), collaborations with the cream of Europe’s avant-garde (?Alos, Pleiadees), numerous solo projects, and the list goes on and on.

His most recent outing is the abrasive, apocalyptic, noise-rock quartet Buñuel. Named after the legendary Spanish filmmaker Luis Buñuel, the band first came together in 2016 and mixes the talents of a trio of Italian musicians—Iriondo, bassist Andrea Lombardini, and drummer Francesco Valente—plus American vocalist Eugene S. Robinson. Their new release, Killers Like Us, is awash in fuzz and rages between brain-crushing, metal-tinged cuts like “A Prison of Measured Time” and “When God Used a Rope” to slow, doomy dirges like “Hornets” and “When We Talk,” as well as moments of unstructured, free improvisation interspersed throughout the record.

BUNUEL - When God Used A Rope (official video)

“We are three Italian musicians,” Iriondo says about Buñuel’s genesis. “We were a little bit famous here in Italy, and we decided to choose an international singer. We wrote to Eugene Robinson, and he accepted our idea. For our first record, the three of us recorded 10 songs in a studio in Italy. We sent them to Eugene in San Francisco, he sang on them, and then sent the tracks back to us. We did that again for this record.” Not only were the vocals recorded separate from the rest of the band, but Robinson didn’t even get a chance to rehearse with them. The first time the band played together as a quartet was onstage in front of an audience. “We didn’t rehearse with Eugene—we rehearsed ourselves—and we met with him the first day of the first gig. That’s how it started.”

Despite Iriondo’s years of experience with group improvisation, that was not the approach he took with Buñuel. You’d think improv would be helpful when stepping onstage raw with an unrehearsed new singer. Rather, the band’s vibe is through-composed songs that are played the same way—except for planned sections set aside for improvisation—night after night.

“When I want to take a solo, I adjust the Cornish directly with my foot. I open up the volume, and then I arrive in the cosmos.”

“We play the songs like they are on the album,” says Iriondo. “Although we do have some parts, or structures, that can change. For example, on our first tour, we wrote our 10 songs, and that’s all we had. At the end of the show, the audience asked for more. I said, ‘Okay, let’s start with an improv,’ and that improv we used on those gigs from the first tour became a song on the second album [“The Sanction” o 2018'sThe Easy Way Out]. We composed each day, each gig, and the song transformed and arrived at the end of the tour.”

When recording Buñuel, Iriondo harnesses that live feel by taking a minimalist approach to overdubs. Aside from an odd guitar solo or two, the instruments are recorded live, with the band members standing together and looking at each other. “I also play pop rock with other bands, and overdubbing is okay for that kind of music, but the wildness of this project gains a lot when we’re all playing together in the same room,” he says.

“In the past, in the ’90s, I used the VHT head system that people talked about,” he says about the now-rebranded Fryette Pittbull Ultra-Lead. “I bought the second one that arrived in Italy in 1994. But in the last 20-to-25 years, I started using theHiwatt DR103, and I think that’s my sound. When I plugged in for the first time, I said, ‘What the hell is this?’ I can go from high-frequency, crystal-like sounds to really deep grunge sounds with a lot of low frequencies. In general, with Buñuel and also Afterhours, I use the Hiwatt, and then also another amp, a 300-watt SWR California Blonde, which is a transistor amp. I have the headroom also in the clean sounds, but when I engage all my fuzzes and boosters, the gain is incredible, and it’s still in front of you all the time.”

“I love this idea, because you can put everything inside the metak. It’s like a collection of your emotions.”

Iriondo’s tone is wild, too. Considering how mangled, heavy, and distorted his sound gets, it’s interesting how he crafts his tone almost exclusively with pedals, which he uses to drive his amps. He owns more than 20 heads and cabs, and his preference is classic British amps like Hiwatt, Orange, Carlsbro, and Simms Watt—he has a few of each in assorted colors—that have a lot of headroom. He feels those work best with his high-gain pedals.

Iriondo has a seemingly endless collection of pedals, too, although his go-to is his signature octave-synth-fuzz-boost Arpiona, made by Italian builders AC Noises. The pedal starts with a gated fuzz circuit inspired by Death By Audio’s Harmonic Transformer, followed by a sub-octave bass synth, more fuzz, and a boost. He uses that in conjunction with an EarthQuaker Devices Acapulco Gold, and a Pete Cornish NB-2 boost that’s always engaged. “When I want to take a solo,” he says, “I adjust the Cornish directly with my foot. I open up the volume, and then I arrive in the cosmos.”

Afterhours - Spreca una vita

They’re Italian, which is probably why this Afterhours video looks like a Federico Fellini film.

Iriondo is also no purist. If an analog circuit will get him the sound he wants, great, but he’s just as happy using a digital device. “I use everything that can give me satisfaction,” he says. “Why not?”

Why not, indeed. He also gets that satisfaction from his guitars. “About 80 percent of my choice in guitars is the feel, and 20 percent is the sound,” he says. “When you’re using some of these destruction pedals on the loud and heavy stuff, the guitar isn’tso important. You destroy everything with these kinds of pedals. They completely destroy your clean sound. Although when I play pop-rock music, I change my guitars a lot.”

But that feel is elusive, which may explain Iriondo’s vast collection of instruments. He has vintage guitars he doesn’t mod at all, but in general he’s an itinerant tinkerer. He usually swaps out pickups, even on his less expensive guitars, and has a significant number of custom-built guitars as well. “I’m not only a collector, I’m a professional, which means guitars are my life,” he says. “I want to have tools that work well with me. In the last few years, I’ve had the opportunity to have my dream guitars that I ask luthiers to build for me with my specific specifications. The principal guitar that I used on the Buñuel project is made by Billy Boy Guitars. It has an incredible tremolo, and it’s a light guitar. All the sounds you hear on Buñuel are made with that guitar.”

Perhaps Iriondo’s most unique instrument is his custom-built Mahai Metak. It’s a 10-string, short-scale table guitar. Six of the strings are tuned to D in different octaves and act as drones. The other four are G, G, F, and A. The instrument has pickups on both ends—near the bridge as well as near the nut—plus an onboard oscillator and distortion unit, and controls for volume and tone. He plays it with an assortment of items, including marbles, roach clips, and steel wool. “I play it with Chinese sticks,” he says, “and I create rhythms and special sounds with steel wool—that stuff you use in America to wash your dishes. It sounds great. I use it with the loopers and reverbs and it creates these noisy and bizarre sounds, as well as melodic sounds that create a nice texture.”

It’s that openness and wonder, as exemplified by Iriondo’s voracious appetite for gear, as well as his embrace of disparate genres and styles, that are the ingredients that make up his metak. Call it his esoteric pile of ideas, which gives him permission to explore the endless energies of his imagination. He’ll conjure up sounds that are heavy and dark—or playful and light—and almost always fun, and, maybe, even a little mischievous.

And isn’t that, ultimately, the ideal?
