During the late noughties Crystabel Efemena Riley toured Japan and Europe using drums, electronics and make-up in power-noise trio Maria and the Mirrors. This was the start of her interest in patterns on skins — human and drum. An interest in dimensional patterns existing on (and off) different surfaces has continued to evolve through exploring the idea of 'care and uncare' of various skin surfaces. Crystabel has been a long-term collaborator with Sue Lynch who welcomed her into the Horse Improvised Music Club and later played in the London Improvisers Orchestra. She is currently working on the multi-format duo project @xcrswx with Seymour Wright and recently released a split vinyl with Lolina.
