Zwerm is an electric guitar quartet based in Belgium and founded in 2007. The group has collaborated with various composers, performers and visual artists. Dallying between pure noise-impro, English renaissance music and contemporary composed music, Zwerm has never strived for a one-sided artistic profile. The common denominator being not so much a particular stylistic view but rather a shared curiosity in all kinds of music.

In 2018, the release of the album ‘Badminton in Tehran’ also marked the birth of Zwerm’s own record label: Time Goes By. This label allows them to promote and publish their own work as well as individual projects by members of Zwerm and other collaborations that fit their general “aesthetic”.
