Killing Is My Business... and Business Is Good! is the debut studio album by American thrash metal band Megadeth. It was released on June 12, 1985, through Combat Records. At the beginning of 1985, the band was given $8,000 by Combat to record and produce its debut album. After spending half of the album's budget on drugs, alcohol and food, the band was forced to fire their original producer and produce the album themselves. Despite the resulting poor production, the album was a well-received effort that obtained strong reviews in various music publications. Killing Is My Business... and Business Is Good! played an essential role in establishing thrash metal as an authentic subgenre of heavy metal music. It explores themes of death, violence, and occultism.
