APO's roster of musicians centers around Blues legends like 93-year-old Henry Townsend (the only musician to have recorded in every decade since the 1920s), Jimmy Rogers (who introduced a young Muddy Waters to the Chicago scene in the 1940s and helped form the first and most-classic Muddy Waters Band), Jimmie Lee Robinson (known as the Lonely Traveler and a man who backed stars like Little Walter, Elmore James and Howlin' Wolf before achieving recording success on his own) and 87-year-old Honeyboy Edwards (one of the last living links to Robert Johnson and the rich delta-style Blues that Johnson made famous).

From there, we've included a few up-and-comers like Jimmy D. Lane (Jimmy Rogers' son and a mean, high-voltage electric Blues guitarist), Harry "Big Daddy" Hypolite (a Blues and Zydeco guitarist who backed Clifton Chenier and CJ Chenier for years before breaking out on his own) and Noah Wotherspoon (a 20-year-old guitar virtuoso whose style pays significant homage to the older Blues masters). And APO offers a few non-blues albums by Folk/Americana singer Nancy Bryan and Jazz singer Myra Taylor.
