Country blues guitarist Paul Rishell and harmonica player Annie Raines’ first fully collaborative CD, I Want You to Know, emphasizes the laid-back songbook of prewar bluesmen such as Blind Boy Fuller and Barbecue Bob. Sure, this duo is merely mimicking the past, but its instrumental virtuosity and charming presentation help make up for the lack of originality. Thanks to Rishell’s ringing, twanging steel-string fingerpicking and Raines’ train-whistle-strong blowing, tonight’s benefit for the D.C. Blues Society should make a Wheaton stage feel like a Southern porch. With D.C.’s Little Bit o’ Blues at 8 p.m. at Phantasmagoria, 11319 Elkin St., Wheaton. $8. (301) 949-8886. (SK)
