Steven Severin is an English musician, composer, bassist and co-founding member of Siouxsie and the Banshees. He took the name "Severin" from the Leopold von Sacher-Masoch character who is mentioned in the Velvet Underground song "Venus in Furs". After the split of Siouxsie and the Banshees in 1996, Severin created his own label RE, and released several instrumental albums via his official website. He regularly performs live in solo, playing music over footage of silent films. Collaborations with Severin include his most notable with former Banshee, The Cure frontman Robert Smith as The Glove. He has also worked with the likes of Jarboe, co-wrote with Marc Almond, produced works by Lydia Lunch and Altered Images and more recently collaborated with Andrew Liles and the late Peter 'Sleazy' Christopherson.
Severin's releases on Erototox Decodings consist of four concept EPs entitled 'Codex Astra', inspired by poetic illuminations by Aleister Crowley.
