A few nights ago I got to see all these acts- Grammatik, Griz, Beats Antique, Savoy, Empire of the Sun, Porter Robinson, Damian Lazurus, Matthew Dear and Paco Osuna. Had only heard of the first 3 mentioned, and Beats was the only act I'd actually heard/seen live before.
Damn though! Griz & Grammatik were fire!! Griz even had dudes come up and sit on on trumpet trombone and saxophone for a few choice cuts. I hadn't really given this kind of music much time before, but it was fucking fun!!
