OK, so I figured out the band I saw, they're kinda this electronic thing (and Redlemon, if I remember right they do have turntables!!!) with the Theremin in the front of the mix. They're called IQU and the album is Sun Q. You can check them out at
www.iquiqu.com. They're asian, some rather asian sounding beats with the theremin and the electronic beats, pretty cool. I'm sure you can listen to snipets on the internet somewhere!
