David Scott “Dave” Mustaine (born September 13, 1961) is an American musician from California. After serving as the first lead guitarist for Metallica, Mustaine was fired as his erratic and obnoxious behavior fueled by alcohol and drug abuse was getting on the bandmates' nerves. On the bus back home, he decided to found his own band. The result was Megadeth, where Mustaine sings, plays guitar, and writes nearly every song.
He currently lives in Nashville, where his daughter Electra Mustaine is attempting a career at country music.
