Love the Choppertone. This guy created his own custom MIDI controller 'instrument' to remix/mash samples on the fly. The tune in the vide is great. The backing beat could use a little work, but not too bad anyway.

Saw Dego from 4Hero perform live a couple years ago at the Brooklyn Masonic Temple (opening for The Herbalizer and some local collective/band who I can't remember), and looked like he had something similar to this. Was a little hard to appreciate the angularity of his tracks in a mostly empty and consequently super-bright room like at the Temple, but was an interesting show nontheless.
