Potts had a couple of LPs of his own without Lacy, also had sideman turns with Robert Wood, Francois Tusques, and others. Excellent player. I agree with Chuck about the sound on these Novus sessions and it was troubling enough that I didn't keep the ones I bought.
Also, FWIW, the Lacy-Waldron on Japanese Victor, mentioned earlier, is a quartet. It's very good.
