Kronos Quartet Recommendations?

I wonder if You folks who like the Kronos Quartet may also enjoy the work of a lesser known group called "The Rachels". Perhaps a bit more Avant Garde and even less predictable than Kronos. I enjoy their albums that were recently introduced to me by a friend, one called "Selenography" and "Systems/Layers". Not sure why they remind me of Kronos, but somehow they do. The Rachels are a much larger ensemble (I think 10 members). Take Kronos and add a bit of Eno, a dash of Gavin Bryars, a splash of Laurie Anderson, perhaps a pinch of the Hillard Ensemble, and a few others I'm not thinking of right now, and there you have yourself "The Rachels". Or maybe not........

...and than you may want to go and check Keith Tippett 50-piece band to get a real feeling of avant-garde.
not sure if available on CD but I have one of few hundreds of prints available in this world...

A bit off the beaten track but definately worth tracking down (perhaps as a download) is the song "Rose Marie" from Don Walser's album, "Down at the Sku-Vu Drive-In." Kronos plays behind Walser on this cut, and the combination of avant-garde and old-school country results in a truly beautiful and moving song, definately a sum greater than its parts.
