The KATABASIS Cycle was a series of multidisciplinary performances in the UK by Petal, working under the pseudonym 'lonely carp'. The concept album and accompanying summoning circles, debuting in Edinburgh's Summerhall, and returning to their anatomy lecture theatre for a weekend of ritual performances to close the cycle, acted as a catharsis of her traumatic experience of survival sex; one all too common amongst trans women. The album was released on Vinyl and Cassette thanks to the Do It Differently Fund, awarded by Help Musicians UK, in 2021.
The performance involved ingestion and regurgitation of flowers (representing the artist-as-survivor) and pomegranates (representing the artist-as-victim), self-paddling, and extended instrumental technique. It was 48 minutes in duration.
