This is What T-Pain Sounds Like Without Auto-Tune

T-Pain, the musician who popularized auto-tune to the extent where he even had his own iPhone app for it, is now showing the world in a concert for NPR, that he can in fact sing without the help of technology.

"People felt like I was using it to sound good," T-Pain told NPR. "But I was just using it to sound different."

Based on this performance, he should probably ditch the auto-tune more often.
