HALS (AUT)

HALS is an experimental a cappella vocal ensemble from Austria, featuring singers Anna Anderluh, Amina Bouroyen, Anna László, and Valerie Costa, all of whom have already made a name for themselves through other projects in Vienna’s jazz scene. They call their music “Free-Fall A Cappella,” creating harmonically complex vocal music with virtuosity and verve. Their repertoire includes unconventional arrangements of compositions from jazz, pop, and contemporary music—by artists such as Jacob Collier—as well as original material. In spring 2025, they released their debut album, Free Fall A Cappella, on Session Work Records.
