"Although Charles Mingus probably could have performed professionally as a pianist, as evidenced on Mingus Plays Piano and Oh Yeah, he was an absolute monster on the bass, as well an incredibly gifted composer. While his bass skills can be heard on the outstanding 1953 Jazz at Massey Hall live album with Charlie Parker, Dizzy Gillespie, Bud Powell and Max Roach, his landmark 1959 Columbia disc, Mingus Ah Um, is hailed by some as his finest recording. It's certainly a great place to start for uninitiated."
