Carrie Rodriguez was a classically trained violinist before she took up country fiddle to back Alejandro Escovedo, Lucinda Williams and Chip Taylor for most of her early career. It was a young musician’s dream: Taylor discovered Rodriguez at the South By Southwest Festival in 2001 and decided to take her on tour withhim to Europe. He then recorded three albums with her in the early ’00s. That apprenticeship allowed Rodriguez to hit the ground running with 2006’s country-minded debut, Seven Angels on a Bicycle. Last year’s album, Love and Circumstance, centers on singer-songwriter twang, particularly the cuts featuring Buddy Miller. Rodriguez’s croon has a husky tinge like honey with a touch of spice, and she takes some clever lyrical turns: She compares someone with a “’50s French Movie” (When do I take my clothes off?) and confesses, I learned all the words of love in my dictionary. Expect more of the singer’s sultry voice and subtle wit at her Acoustic Café Tour date at Knuckleheads.
