I did some searching and found some more 18th Street Lounge music floating about in the blogverse.
Here's what I found through The Hype Machine:
Live at the Breezeblock (via totally fuzzy)
Dc 3000 (via a best truth)
heaven's gonna burn your eyes
all that we perceive
exile (all via tmwsiy*)
until the morning comes (kid loco rmx) (via mookamotel)
Warning Shots (via Feel Me Good Tunes)
The Gnomes (via Scenestars)
Also, be sure to check out the official websites for 18th Street Lounge, Thievery Corporation, Ursula 1000, Thunderball and Chris Joss.
