This singer-songwriter-pianist scored a minor hit in 1973 with “Avenging Annie,” a rambunctious yarn about Annie Oakley and Pretty Boy Floyd that was later covered by Roger Daltrey. Since then he’s stayed below the radar: though he never stopped recording and performing, his 1979 conversion to Christianity (and overtly Christian music, at least for a while) and his subsequent move to Europe pretty much sealed his fate as a cultish obscurity. But that doesn’t seem to bother Pratt one bit. On Live at the Village Underground (itsaboutmusic.com), a 2003 concert recording, his angelic, impish voice is in fine form, and he plays his unique sort of white-soulful folk-glam with high-spirited zeal–imagine Nick Drake with a backbone or Donovan with testicles. Pratt returned to his native Boston a few years ago and in 2005 reissued his entire catalog online; a self-published memoir, Shiver in the Night, is forthcoming. For this show he’s backed by three locals: guitarist Michael Lyons (Clyde Federal), bassist Greg MacAyeal, and drummer Geoff Greenberg (Mr. Rudy Day). Frisbie headlines. a 10 PM, Schubas, 3159 N.
