Neslort, Mystical Scam (Lort/Threadhead). Most reviews and articles about the leader of Neslort (spell it backward) begin, “Eccentric New Orleans trombonist Rick Trolsen…†The reasons for that are apparent in this CD. Equally evident is Trolsen’s and the sextet’s musicianship, which merges street funk, bebop, electronica, rhythm and blues, New Orleans parade pzazz and—as in all good gumbos—a mystery ingredient or two. Tim Robertson’s pliant guitar licks, Kyle Cripps’ saxophones, Matt Perrine’s bass and tuba, Larry Sieberth’s keyboards and the popping vigor of Boyanna Trayanova’s drumming complement Trolsen’s blowsy trombone and his vocals, reminiscent of David Clayton-Thomas.
