Megadeth are a Grammy-winning, Los Angeles-based thrash metal band founded in 1983 by Dave Mustaine after he was kicked out of Metallica. In 1985, they released their debut album Killing Is My Business... And Business Is Good! on Combat. While Mustaine separated himself from his previous efforts, he kept going with thrash metal and continued to help define the genre. The record has since gone on to become considered a classic. Megadeth has continued playing to this day, releasing more than a dozen records. This original Megadeth shirt, with fading and the bottom seam coming undone, is from their tour in support of their debut record.
