I reccomend The Baldwin Brothers, I first heard "Urban Tumbleweed (featuring Barron Ricks)" on the game Amplitude which was funky and upbeat. So I downloaded some more of their songs (which are hard to find) and then bought "Cooking with Lasers" which is a great CD. They say they're "Chicago Junktronic".

"Premature Jazzulation"
"Highway Patrol"
"The Bionic Jam" (jazzy electronic)
"That's Right"
"Funky Junkyard"
"Are you there Margret, It's me God"
All great songs.
Also, Lavender Hill Mob's "Endless Handbag"
Due to mp3.com's new 3-song rule they only have a few..
