Group from United States
About Six13
Six13 is a New York–based Jewish all-male a cappella singing group. Formed in 2003, the six-voice group is known for parodying contemporary pop songs by adding Jewish themes and lyrics. It also sings cover versions of pop hits and Yiddish and Israeli classics, and produces original compositions based on traditional Jewish prayers. Relying solely on vocals, the group achieves the effects of guitar, bass, drums, and electronic music through beatboxing and multiple layering of vocal tracks on its music videos. The group performs regularly for universities, synagogues, public and private groups, and in music festivals. It has released eight albums and won numerous awards.
