There is a cool new gear-focused video series called Echoes. Dwarfcraft has paired up with PureSalem Guitars to show off some great gear in strange locations.
Episode 1: Space, is beautifully shot, featuring Jaime Hansen (The Ronald Raygun) and Matt Haapala (The Ronald Raygun, The Heart Pills, Pit Wagon) and Mike Noyce (Bon Iver) improvising in a racquetball court.
Most loopers who do time based loops tend to work alone. If they use bass and drums as part of their act, they layer the instruments themselves. Rarer are loop-based performers who work with a live bassist and drummer. Teddy Kumpel has perfected the art of looping with a rhythm section through his steady gig at the Rockwood Music Hall in New York City. It helps that his locale offers him a menu of the best rhythm sections in the world to work with. Kumpel was kind enough to explain how he keeps the sections in sync, before leaving on tour as guitarist for Joe Jackson.
