Though Kevin Olusola ’11 just won a Sony Music recording contract with his group Pentatonix on NBC’s “The Sing-Off,” we don’t have to wait until the album drops for more music from the beatboxing cellist.

Olusola collaborated with singer-songwriter Antoniette Costa and classical violinist Tara Kamangar to release the video for their new single “Stranded” on Thursday. The song is written by Costa and based on the novel “Rebecca” by Daphne du Maurier. If you missed Olusola’s cello playing while he competed with his a capella group, don’t worry—KO shows off his simultaneous beatboxing and cello playing in “Stranded.”

Costa and Olusola released the video for their first single “Void of a Legend” in August. The song reached the #4 position on the iTunes Classical chart.

Check out the video for their new single below.
