Fans of the bizarre, the occult, and the avant-garde gather tonight as the Residents kick off their first national tour in six years. Dressed to the nines in evening attire — complete with top hat, tux, and giant eyeball mask — the group regales audience members with ghoulish tunes, haunting orchestral renditions, and experimental expressions from a discography that stretches across four decades. For those seeking the identities of rock music's most anonymous collective, this might be your final opportunity: rumor has it that after this tour, the Residents say "Good Night" for good.
