I have been listening to tons of Mal's albums. They are pretty much all very good to great, kind of super hip for what ever period. He leaves a ton of room for the bass. The early trios have incredible bass playing from guys like Addison Farmer and Juilan Euell, both of those guys are super crisp and clear. Amazing players. Here is a clip with Euell: Truthfully, their best work, and some of the best music ever is the Waldron and Lacy duo, but this quartet is nice.
