Although Robert Pollard (in Guided By Voices and his many side projects) is most associated with two-minute lo-fi pop songs, his band Circus Devils is an homage to vintage psychedelic and progressive rock in the manner of King Crimson, Hawkwind, and others. Pollard's regular collaborator Todd Tobias and his brother Tim Tobias are his foils in this act; Pollard limits himself to lyrics and singing, with Todd Tobias providing the majority of the music. Starting with 2001's RINGWORM INTERIORS, each Circus Devils release has been a concept album with a specific theme and musical style.
