His guitar solos are sharp, inventive, playfully arrogant, and have the power to transform any song into an epic crescendo. But album after album, Gary Clark Jr. has revealed himself to be an even more complete artist. This composer and singer regularly turns off his distortion pedal in favor of classy R&B or retro-futuristic gospel. In fact, it was for the sweet vintage soul title “Please Come Home” that the Texan received a Grammy Award in 2014. On stage, however, one thing is perfectly clear: Gary Clark Jr. is, above all else, a blues musician. You only need to listen to his mind-blowing work with the Rolling Stones, B.B. King, Eric Clapton, and Buddy Guy to be convinced. This summer, Gary Clark Jr. is performing for the first time at the Festival, and he has a fresh new single in hand: a Homeric version of the Beatles classic “Come Together”.
