In 1984, Megadeth recorded a three-song demo tape featuring Mustaine, Ellefson, and Rausch. The demo tape, "Last Rites", was released on March 9, 1984. It featured early versions of "Last Rites/Loved to Death", "The Skull Beneath the Skin", and "Mechanix", all of which appeared on the band's debut album. The band was unable to find a compatible second guitarist. Kerry King of Slayer filled in on rhythm guitar for several shows in the San Francisco area in the spring of 1984. Afterwards, King went back to Slayer and Megadeth replaced Rausch with jazz fusion drummer Gar Samuelson. Samuelson had previously been in the jazz band the New Yorkers with guitarist Chris Poland. After seeing Samuelson perform with Megadeth as a trio, Poland went backstage and suggested an impromptu audition as lead guitarist for the band; he joined Megadeth in December 1984.
