New York’s BB King Blues Club will host Organ-Asm, an evening-long celebration of the organ, on June 29. The show will bring together four very different organ players: Al Kooper, The Band’s Garth Hudson, Greyboy Allstars’ Robert Walter and Marco Benevento. The four musicians will be backed throughout the night by bassist Will Lee (The Fab Faux), drummer Anton Fig and guitarist Oz Noy. The show is part of the Blue Note Jazz Festival.
