More recently, Haircuts for Men: https://youtu.be/XZUiPCGjej8
I also like this rendition of Piano Counterpoint: https://www.youtube.com/watch?v=LM4t2Kvpv0Y
If you like Steve Reich, I'd also recommend Oneohtrix Point Never - R Plus Seven (and all his other albums pretty much).
I think the 'trance-like state' is what I find relaxing. It's basically meditation. I've been listening to the ECM recording since I posted that, and I'm realizing that's not my preferred recording. I really like the recording done by the Grand Valley State University New Music Ensemble: https://www.youtube.com/watch?v=0xzyzgqEk5U&list=PLkqUzfbYHJ...
Also, this version by Rough Fields, which uses non-standard instrumentation: https://www.youtube.com/watch?v=DULIr7kskM8&list=PL21HssoFMq...
