Siouxsie and the Banshees were a British rock band formed in London in 1976 by vocalist Siouxsie Sioux and bass guitarist Steven Severin. They have been widely influential, both over their contemporaries and with later acts. The Times called the group "one of the most audacious and uncompromising musical adventurers of the post-punk era".

Steven Severin is an English songwriter, composer, multi-instrumentalist and producer. He is best known as the bassist of the rock band Siouxsie and the Banshees which he co-founded in 1976. He was also a member of the short-lived band the Glove. 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. In the late 2000s and the early 2010s, he regularly performed live in solo, playing music over footage of silent films.
