Beatboxing group Berywam had the America's Got Talent judges transported to a music festival with their a cappella takes on EDM songs. The excitement continues into the next round this week, and Billboard has an exclusive clip.

Beatness, Rythmind, Wawad and Beasty of the group took the stage to perform a rendition of Chris Brown's "Look at Me Now," as they nail the lightning-fast Busta Rhymes rap. Judges Gabrielle Union and Julianne Hough are visibly impressed, as they remain with their jaws dropped, bopping along to the beat.

Check out the clip above, and catch the full episode Tuesday (July 16) at 8 p.m. ET/PT on NBC. The episode marks the start of judge cuts, with country superstar Brad Paisley as the first guest on the panel.
