This band, featuring a constantly rotating cast of over 35 Chicago bluesmen (hence the 'mystery' moniker') traffics in rough-and-tough blues that slips into jazz territory every once in a while. The mystery revealed this week 'round is unsung shredder Osee Anderson, a burly Chicagoan who got his start on Alligator Records sessions as Lonnie Brooks's lead and rhythm guitarist. Three self-produced records later, Anderson pays respects to his mentor, Willie Dixon, with attention to speedster percussion, glossy keys and off-mic wails. His sound is neatly summed up by the title of his debut LP, Old School, Nu School. (Gavin Paul)
