Poison Ruïn formed in Philadelphia in 2020. It began as a solo recording project but developed into a full band by the end of the year. Their music combines classic anarcho/crust punk with a variety of influences including oi!, american post-punk, NWOBHM, and dungeon synth. The band heavily utilizes dark medieval imagery and lyrical themes combined with anarcho iconography. A compilation of their 2020 demos was released as an LP in 2021, followed by the ‘Not Today, Not Tomorrow’ 7” in 2022.
