Hooteroll?
Hooteroll? is a jazz-rock fusion album by Howard Wales and Jerry Garcia.
Prior to making Hooteroll?, Wales and Garcia had played together at Monday night jam sessions at The Matrix in San Francisco. Wales had also played organ on several tracks of the Grateful Dead album American Beauty.
Hooteroll? features a few musicians who later played in Jerry Garcia side projects — John Kahn ( Jerry Garcia Band and many other Garcia related groups), Bill Vitt ( Merl Saunders and Jerry Garcia), and Martin Fierro ( Legion of Mary).
