Ellen Degeneres is no stranger to introducing new talent to the world. She (or her staff) is known to comb the the interwebs in search of great artists who are making a splash on Youtube and such. There was Rin on the Rox and Joseph Vincent, and now we can add Sam Tsui to the list. Check it out as he performs his previously released Explosion medley. Barring a couple minor nervous hiccups, they did pretty well. Way to do it big on the broadcast stage!
