Washington’s suburbs have long been a focus for capable, slightly rootsy adult-rockers like Laura Shawen, whose This Time signals her exurban domesticity with a picture of a “Shawen” mailbox on its back cover. This singer/songwriter, however, gets the slightly funky, mildly countrified balance righter than most. The trick is both in Shawen’s songs (catchy, if unsurprising) and her voice, big and deep enough to provide a soulful contrast to the twang of her violin- and steel-guitar-outfitted band. From here, Shawen can go either folk (as on “Footfalls,” with pretty harmonies by violinist Helen Hausmann and bassist Judith Quinlan) or rock (as on a moderately thumping version of Buffalo Springfield’s “For What It’s Worth” that alternately spotlights Hausmann, Quinlan, and guitarist John Penovich). To order a copy of the CD, call (301) 548-0823, which also dispenses the singer’s show schedule.
