T-Pain stopped by NPR's Tiny Desk Concert series to perform some of his classic hits (ahem, "Buy U A Drank"), without auto-tune. "This is weird as hell for me," he said.
In the mid-2000s, T-Pain was known for his liberal use of auto-tune, but in the 13-minute video below, he displays a natural talent. Next week, he'll release a greatest hits album. That one will feature auto-tune.
