Nosaj Thing is lovely. I've seen him live a few times here in Amsterdam. He's not touring a lot since he apparently had a major mental crackdown or something..
Anyway if you're looking for this kind of crazy stuff then dive into the following artists: Shlohmo, Lorn, Flying Lotus his older stuff, EPROM, Deru (get his third album it's fucking good).
And some labels like Rwina Records, Brainfeeder.. maybe Alpha Pup.
