For an artist as perpetually re-inventing as Mingus, it's almost a given that one album will be very unlike the next. OH YEAH is, in fact, quite different than the bassist/composer's other releases for two reasons: Mingus plays piano throughout the entire set, and he sings--not the standard grunts and exhortations that one usually hears from Mingus as bandleader, but an actual hoarse, blues-rattled vocal directly into the microphone.
