Part of a growing legion of female blues guitarists to receive national attention, Debbie Davies paid her dues for over 15 years as a side musician with a number of groups, most notably the late Albert Collins’ Icebreakers. Now the leader of her own band, the California native showcases her axework and vocals on Loose Tonight, a collection of largely self-penned Texas- and Chicago-style bar-band blues arrangements. At 9 p.m. at Fleetwood’s, 44 Canal Center Plaza, Alexandria. $9. (703) 548-6425. (Steve Kiviat)
