Excitement was in the air this morning as Nachum hosted members of the amazing Jewish A Capella group Six13 live in the studio to officially debut their latest CD, “Vol. 6: Thirteen” and have them perform some songs on the air. “For 13 years, they’ve pushed the boundaries of Jewish music and redefined even our own understanding of the artistry that can be achieved with the human voice. And now Six13 breaks new ground with their latest release, ‘Vol. 6: Thirteen.’ Early consensus is that this is by far the best Six13 record yet. Featuring fantastic new original songs, popular covers and hit viral parodies, Six13 ‘Vol. 6: Thirteen’ celebrates the group’s ‘Bar Mitzvah’ with unprecedented flair. On top of it all, the album features killer guest vocals from Israeli superstar Gad Elbaz (on a cover of his mega-hit “Hashem Melech”) and popular vocal trio The Zemiros Group.”
