Donald "DJ" Johnson is the percussionist for, and one third of, the Texas trio Khruangbin, which released its fourth studio LP called A La Sala in April. The band that draws inspiration from funk, soul and psychedelic rock made all across the globe is currently touring the states and playing A La Sala front-to-back. They also play Bonnaroo Music & Arts Festival in Tennessee June 14. Hear Johnson describe dusting off the rust to prepare for touring this year, how the band continues to grow and connect with each record, how festival sets necessarily differ from Khruangbin headlining shows and an item he's learned he cannot live without while traveling.
