For the past two decades, Dean Wareham has personified the Velvet Underground lineage within modern rock, crafting cool, understated music (dubbed slowcore) through a series of groups: Galaxie 500, Luna and now DEAN & BRITTA with his girlfriend Britta Phillips (who used to be in the Atlanta pop band Ultrababyfat). The pair's latest album, Back Numbers, maintains Dean & Britta's status as one of indie rock's sexiest couples. They arrive at the Variety Playhouse on Fri., MARCH 23, with Cortney Tidwell opening. $15. 8:30 p.m. 1099 Euclid Ave. 404-524-7354. www.variety-playhouse.com.
