Former Grateful Dead keyboardist Tom Constanten has taken over Vince Welnicks spot alongside Gent Treadly over a decade after Welnick replaced one of Constantens successors in the Grateful Dead (got that?). Tomorrow the keyboardist will perform with Gent Treadly at Sedona, AZs Casa Rincon, before wrapping up his current outing in Flagstaff, AZ (11/18) and Las Vegas (11/19). Constanten will celebrate New Years Eve at Colorado Springs City Auditorium as part of a revue which includes Jefferson Starship and Quicksilver, among others.
