Indeed. Those three albums are stellar, IMO.
ECM reissued them in one of their plain-white-box sets.
I only got to see him play one time also, just before COVID hit. It was a show at Mezzrow, a duo performance with Dave Liebman. Saw both sets. Most memorable was a LONG, way way out version of "Green Dolphin Street." I had a chance to chat briefly with Richie between sets. I said, "I've NEVER heard 'Green Dolphin Street' like THAT." Richie smiled and said, "I haven't either!"
It's interesting that both Beirach and Liebman -- for different reasons -- had a falling out with Manfred Eicher.
