Dave Mustaine – Career

Panic, Metallica, Fallen Angels

Mustaine started his career in 1978 with the band Panic. It had Mike Leftwych on drums, Bob Evans on bass, Tom Quecke on rhythm guitar, Pat Voeks as a vocalist, and Dave Mustaine as the lead guitarist. 

But after Panic’s second show, Leftwych and a sound man were killed in a car crash and the band started to fall apart in 1981.  Rhythm guitarist Tom Quecke also passed away. 

In 1981, Mustaine joined Metallica as the lead guitarist after its drummer Lars Ulrich had placed an ad in a local newspaper. But his membership with Metallica ended in 1983 before recording their debut album. He had however worked with the band in several demos and co-wrote 6 tracks.

The primary cause of his early release was due to his struggle with alcohol and drug abuse, overly aggressive behavior, and personality clashes. After his departure, he worked as a telemarketer. In April 1983, Dave Mustaine founded the band Fallen Angels alongside Robbie McKinney, Matt Kisselstein, and later Dave Ellefson, Greg Handevidt, and Lawrence Renna ('Lor' Kane). The band was later renamed Megadeth.
