Listening to a few K7 cds I picked up cheaper than normal. Daddy G: DJ Kicks - you know, one of the Massive Attack guys; Kruder and Dorfmeister: DJ Kicks, maybe better than the K & D Sessions (maybe); and the first of Peace Orchestra.
You can hear real audio versions of them on the K7 website by following the above links. A good way to try before you buy. That's what I did. They ask you to sign up but it costs nothing and they've never bothered me.
