San Jose, CaliforniaPerhaps the Mumlers were channeling the spirit of William Mumler, a mid-19th-century man famous for claiming he could photograph ghosts, but once all six band members touched their fingers to a Ouija board's planchette, the board, they claim, spelled out their group's name.

Regardless, it's clear their swaggered ruckus pop channels dead folk musicians galore. Despite the ghostly origins of their handle, the Mumlers' live appearances tend to turn into lively celebrations, with the outfit dancing about the stage.

Their repertoire of instruments rivals any philharmonic's and includes guitars, drums, upright bass, various keyboards, euphonium, French horn, trumpet, clarinet, tambourine, pedal steel, and recently, eagle whistles from Mexico.
