Wu-Tang Clan was outperformed by an unexpected woman during the rap group's set at Bonnaroo last week. Holly, an American Sign Language translator hired to interpret the rappers' lyrics for the deaf, performed with as much vigor as those onstage.

No one expected her to give such a dramatic, emotion-filled performance as RZA, Method Man, Ghostface Killah and more spit out their lyrics.

In the video of the stage show, Holly is shown bopping to the beat and throwing out hand signals. Obviously, she's a true hip-hop fan, keeping up with the fast-paced delivery of the rappers.

Holly even lent her talents to R. Kelly as he took the Bonnaroo stage, signing for him during his performance of 'Ignition.'
