In all manner of settings, from solo concerts to large group situations, multi-instrumentalist Ken Vandermark has proven his mettle as a fearless and resourceful improvisor. So when two-fifths of his new Edition 55 band were not available to tour, he added a new piece to the remaining players and rechristened the band Edition Redux.
But the story doesn’t end there. The new player, keyboardist Erez Dessel, couldn’t make the tour’s first gig, Vandermark did the math and made 3=2+1. Call it new math or even New Addition, but any way you look at it, Saturday’s New Ghosts concert at BOP STOP—one set by drummer Lily Glick Finnegan with tubist Beth McDonald and a solo set by Vandermark—adds up to an intriguing look at the ever-dynamic Chicago scene.
