Robert Walter hails from the Greyboy academy of jazz. Spirit of '70 is a solid outing for him, but the funk/jazz legend Gary Bartz steals the show. On tracks like "Corey's Snail and Slug Death," Bartz plays with restraint, frothing with fresh ideas and confidently reaffirming his status as an underrated jazz giant. "Volcanic Acne" is the most cohesive track on the album and shows just how exciting Walter's playing can be when he's inspired. Walter's desire to re-create the "'70s spirit" unfortunately fails to reinvent it.
