Siouxsie and the Banshees were among the longest-lived and most successful acts to emerge from the London punk community; over the course of a career that lasted two decades, they evolved from an abrasive, primitive art punk band into a stylish, sophisticated unit that even notched a left-field Top 40 hit.

Throughout its numerous lineup changes and textural shifts, the group remained under the leadership of vocalist Siouxsie Sioux, born Susan Dallion on May 27, 1958. She and the Banshees' initial lineup emerged from the Bromley Contingent, a notorious group of rabid Sex Pistols fans; inspired by the growing punk movement, Dallion adopted the name Siouxsie and formed the Banshees in September 1976. In addition to bassist Steven Severin and guitarist Marco Perroni, the band included drummer John Simon Ritchie, who assumed the name Sid Vicious; they debuted later that year at the legendary Punk Festival held at London's 100 Club, where their entire set consisted of a savage, 20-minute rendition of "The Lords Prayer."
