Six13 סיקס13

Six13 formed in 2003 as a six-voice a cappella group that takes popular songs and gives them a Jewish twist, from Chanukah and Purim parodies to original compositions based on tefillos. Using only their voices, including beatboxing, they create the sound of a full band and have released eight albums over the years. Their videos, like holiday-themed parodies, get huge views online.
