Only Instrumental Trip-Hop?

I'm lookin to get some recommendations on instrumental "trip-hop" music to check out. I'm really a hip-hop head, but I've been gettin more into other genres of similar music. Here's the kinda more I guess "trip-hop" stuff that I'm already into:

DJ Krush "Kakusei"
DJ Shadow "Entroducing"
Amon Tobin
Andrea Parker "Kiss My Arp" instrumentals

Anyone have any recommendations on music similar to this? I'm looking for just instrumental stuff with no vocals. Thanks a lot for any help.
