Fabulous recording. The whole thing makes up the last two CD's of the Elvin Jones Mosaic set. Mainly tenor, yes. Exclusively, I can't recall, and don't have the set here in front of me. Liebman is superb, too. A great example of two tenors utilizing the lessons and vocabulary of 'Trane in a very positive way, five years after his death, and after the dust had settled down, so to speak.
