Megadeth could not find a second guitarist that worked well with the band. Kerry King from Slayer played guitar for some of the band's concerts in San Francisco in early 1984. After the concerts, King went back to playing with Slayer. Megadeth replaced Lee Rausch with jazz drummer Gar Samuelson in October 1984. Before joining Megadeth, Samuelson was in a jazz band with a guitarist named Chris Poland. Poland watched Samuelson playing with Megadeth and told Mustaine he wanted to play with the band as well. He joined Megadeth in December 1984.
