From 21 to 23 April 2023 Supermetall on Baumanskaya turned into the Shum art festival: work by around 40 artists, graffiti performances, an auction, talks and a party in an underground car park (Afisha Daily).

On the first night — live sets by Saluki, Truwer and Boulevard Depo. DJ Worm joined Truwer on stage: scratches over a live show under concrete vaults.
