Dub FX - beatboxer/rapper/voice artist/street performer
really just making this thread to say he is awesome and make sure anyone who hasn't seen him does. but what the man does is amazing, and really makes you think in terms of making a lot out of little, the sum being way more than the parts.
he runs his microphone into a bunch of Roland pedals and a Boss sampler, and has delays and effects. he'll beatbox, loop it, and make bass and melodies with his voice, then followed by rapping in different tones thanks to transposition modules. i think it's fun as hell, great music, and awesome to watch:
