I am finding the M22's like to be fed a diverse, but high quality diet.

Eno
Kate Bush
Wayne Shorter
Carla Bley
Porcupine Tree
Lygeti
Medeski, Martin and Wood
Amon Tobin
Tom Ze
King Crimson

And the list goes on...

I do find, like it's proud owner, that it's favorite is Zappa and all manner of progressive rock and jazz. ;\)

And a classical music diet evokes euphonic bliss in all who come within audible range. I have a feeling my collection of symphonic music will only grow larger and larger!
