fat_knuckleTuesday, October 6

Rumor has it that Fat Knuckle Freddy is the latest incarnation of local blues-rock phenomenon Al Giusto (Meantone), which is good news for anyone who digs down-and-dirty guitar in the Mississippi Delta style. Starts at 7 p.m. at Blue (650 Congress St., Portland). No cover (donations accepted; all ages). 774-4111. portcityblue.com.
