Dave Mustaine is  the co-founder, guitarist and lead singer of the thrash band Megadeth. He was the lead guitarist of Metallica, in the early days, but he was fired, due to conflicts. Dave composed many of the songs from their first album, Kill ’em All, but he was not credited. He formed Megadeth, with Dave Ellefson, and set out to create music that was faster and heavier than Metallica. They became one of the “Big Four” of thrash metal bands, along with Anthrax, Metallica and Slayer. These bands became the core of thrash in the early 90’s and influenced the genre and bands that followed. The great thing about Megadeth, is consistency in style and quality. Dave possesses superior guitar skills, and is known for his spider chord technique.
