Twelve is an award-winning vocal group led by Tijs Krammer. We rehearse in Utrecht, but the singers come from all over the Netherlands. In October 2022, Twelve won the Balk Top Festival, the most important festival in the Netherlands for choirs and vocal groups in popular music, held every two years at De Doelen in Rotterdam.

Twelve has been around since 2016 and has already created four full-length performances. Most of the repertoire is arranged by the group itself.
