Downtown Rocks closes its free summer concert series with a whole lotta GARBAGE -- the band, that is. A heavy throwback to '90s alternative (could we expect any less of Butch?), the latest album, Bleed Like Me, finds the band in a darker place, exploring heavy issues including teenage cutters, creepy sex and Prozac-era depression. Show up early for the Aug. 13 performance: The band's last show in Atlanta -- a mere four months ago -- was sold out.
