For the band’s Holy Mountain set, the dual-guitar attack of The Bros. Landreth was held down by lead guitarist Ariel Posen and frontman/guitarist Joey Landreth. Posen used his Duesenberg Double Cat most of the set because “it is so beautiful and well made. They're extremely reliable and stay in tune all the time, and it’s a great balance with the 335.” When Landreth helped out on electric duties, he grabbed his Ry Cooder-inspired Strat that has gold-foil-style pickups and a modded set of baritone strings on it (.068, .056, .044,.024, .020, .019).

2015 marks South by Southwest’s 28th year as a destination festival in Austin’s beautiful neighborhoods like South Congress, East Austin, and downtown along 5th and 6th Streets. Since its inception, SXSW has tried to serve all music fans with a healthy dose of underground and unsigned acts representing nearly every musical genre imaginable. This year was no different with over 2,200 acts that descended upon the Lone Star State’s capital for five days and nights. Premier Guitar had boots on the ground and here is a fraction of the guitar-centric highlights from the event.
