That's a guiding principle for NOVO's three nights. With two stages set up inside the Windup Space, sets ping-pong from the front of the room to the back, with little downtime between the 10 bands playing Friday and Saturday night. Headlining the first night is a rare treat, the Chris Pumphrey Sextet. Pumphrey is a vital performing and arranging presence in local music, not only one of the many saxophones powering the indelible Baltimore Afrobeat Society, but the guy who transcribes and directs the large ensemble. His sextet seems to play out only occasionally, and musically it flows from big-band jazz ecstatic to 1970s Miles Davis outer limits. Also playing Friday is the New York trio DEVL, which splits the difference between noise-rock power trio and prog excursion; Super Sharp Shooter, the local, sax-led approach to the rock power trio featuring reeds bellower Anna Meadors, bassist John Paul Carillo, and drummer Nick Palmisano; and Peals, the duo William Cashion (Future Islands) and Bruce Willen (Double Dagger), who craft a chilled-out living room of looping guitars and effects.
