Five years since the release of his last album, This Land, Austin rock maestro Gary Clark Jr. returns with new whopper JPEG Raw (an acronym for Jealousy, Pride, Envy, Greed … Rules, Alter Ego, Worlds) on March 22. Alongside the magazine’s other SXSW offerings, SPIN presents Clark’s only gig before release of the record, which features icons Stevie Wonder and George Clinton, trumpeter Keyon Harrold, Valerie June, and Naala. The evening promises a special surprise guest, and tickets start at $95.05. – Rachel Rascoe
