My Bloody Valentine experienced a number of line-up changes during their initial months. Lead guitarist Stephen Ivers and bassist Mark Ross were recruited in April 1983 and the band would often rehearse near Smithfield and Temple Bar in rehearsal spaces owned by Aidan Walsh. Walsh, who booked some of the band's early performances, said the rehearsals were "too noisy" and "crazy" that "next door were giving out hell". Ross left the band in December 1983 and was replaced by Paul Murtagh, who left the band in early 1984. In March 1984, Shields, Ivers and Conway recorded the band's first demo on a four-track recorder in Shields' parents' home in Killiney. Shields and Ó Cíosóig overdubbed bass and drum tracks at Litton Lane Studios, and the tape was later used to secure a contract with Tycoon Records.
