Time to shine on stage
Are you an aspiring musician looking for a place to jam, make connections, and hone your sound? After certain concerts, the lobby transforms into a sweltering jazz club where the new generation of musicians mixes with the vibes of the big stage.
Each night, a different punishing band from the KASK & Conservatory opens the jam, and then the stage is open to everyone. Bring your own instrument, join in and make yourself heard! If you're lucky, the main act will stay for a while and you'll get to play with them.
