Warren Haynes, Sonya Kitchell and Dave Matthews Band/Lettuce trumpeter Rashawn Ross all made surprise appearances at New York’s Rockwood Music Hall Stage 2 last night. As previously reported, the free show featured performances by Living Colour’s Corey Glover, Warren Haynes band singer Alecia Chakour and Lettuce/Warren Haynes Band mainstay Nigel Hall. Chakour’s backing band was something of a super group featuring guitarist Sam Cohen (Apollo Sunshine/Yellowbirds), Soulive/Lettuce keyboardist Neal Evans, bassist Alex Chakour, Antibalas/Superhuman Happiness drummer Miles Arntzen and a horn section that included Cheme Gastelum (Dap-Kings, 20th Congress) and James Casey (Soulive) . Surprise guest Sonya Kitchell also sang with the group while Glover sat in on Jimi Hendrix’s “Crosstown Traffic.”

For his set, Hall led a band featuring Lettuce’s Adam Deitch, Eric Krasno and Adam Smirnoff as well as vocalists Tania Jones and Mel Flanner. Like all Nigel Hall Band shows, Krasno played bass. Alecia Chakour also returned to the stage to sing with the ensemble. Meanwhile, Evans emerged for a stretch of songs—on one number he even sat at the piano with Hall. By the end of the night, almost all of the musicians who had played throughout the night had joined Hall on stage (though some musicians had to sit on amps to make room for all the guest players). Most notably, both Warren Haynes and Rashawn Ross emerged at the end of the night to join Hall and his band for a cover of Curtis Mayfield’s “Move on Up.” Haynes is not only touring with Chakour and Hall but also sat in with Ross’ bandmates Dave Matthews and Tim Reynolds on Saturday night.
