This was purely awesome! Mr. Schub and Mr. Koopman both have a style that is unique unto himself. Seeing them work together like this, it's evident that their two stlyes mesh together extraordinarily well. That, coupled with the fact the these two are phenomenal musicians and performers, made this video really great to watch. Thank you Sean at DCT for bringing us this video!
