After a series of unsuccessful vocalist auditions, Mustaine elected to take on vocal duties himself in addition to playing lead and rhythm guitar. In 1984, Megadeth cut a three-song demo with drummer Lee Rausch, who replaced Carruthers after Mustaine and Ellefson decided they couldn't trust him. Carruthers had chosen to hide his black heritage from them by claiming he was Spanish, and they couldn't understand why he would deceive them since they weren't racist. Kerry King joined the band for a few shows; however, he opted to leave Megadeth after less than a week so he could continue working on his own band, Slayer. Jazz-influenced drummer Gar Samuelson replaced Rausch, who left after Mustaine convinced him to play with a broken foot. Megadeth recorded a demo as a three-piece band, which captured the attention of guitarist Chris Poland, also a jazz player and a friend of Samuelson, who subsequently joined the band. In November, the band signed a deal with Combat Records and began touring.
