Atlanta-based rock trio Marvelous 3 will call it quits following an Aug. 3 performance at On the Bricks, Atlanta's hugely popular new weekly free downtown summer music festival, Billboard Bulletin reports. The group's two Elektra albums -- 1999's "Hey! Album" and 2000's "Ready Sex Go" -- sold a combined 133,000 units in the U.S., according to SoundScan. The debut album featured the single "Freak of the Week," which hit No. 5 on Billboard's Modern Rock Tracks chart.
