Local guitar hero Warren Haynes (vocals and guitar) doesn’t know how to sit still. He’s seemingly always performing, recording, touring or sitting in with someone else. And with a new Gov’t Mule album, the politically charged Revolution Come … Revolution Go, recorded last year on Election Day, due to arrive in just a few weeks, one of the hardest working men in show business is back out on the road with comrades in bluesy Southern-rock jam-band arms Matt Abts (drums and vocals), Danny Louis (keys and vocals) and Jorgen Carlsson (bass). Tomorrow night at SummerStage in Central Park, Gov’t Mule (above, performing “Blind Man in the Dark” at Lockn’) arrive with the like-minded Chris Robinson Brotherhood—the former Black Crowes frontman (vocals and guitar) alongside Neal Casal (guitar and vocals), Adam MacDougall (keys and vocals), Tony Leone (drums) and Jeff Hill (bass). The CRB’s most recent release, Betty’s Self-Rising Southern Blends, Vol. 3 (stream it below), out in March, is filled with live soundboard mixes by famed Grateful Dead audio engineer Betty Cantor-Jackson, terrifically capturing the band live, which just so happens to be the best way to experience Gov’t Mule and the Chris Robinson Brotherhood. So don’t miss them live tomorrow night at SummerStage.
