DJ Shadow is pure class, "Number Song" and "Building Steam With A Grain Of Salt" from Endtroducing / "Blood On The Motorway" and "You Can't Go Home Again" from The Private Press being personal faves. If you are into d & b you should check out Photek, the early stuff is very minimalist but Solaris is more expansive.
Yeah, Shadow is class!!! The 6 day war is a particular favourite of mine, there is also a Bad Company jungle remix of it which is pretty good too!!!
I've been listening to Photek for a few years, it's the kind of stuff you can sit and chill too, saw him at a rave in Manchester in August and his set was really good!!!
