When it comes to the titans of thrash metal, few bands have had the impact or longevity of Megadeth. As one of the “Big Four” of thrash metal alongside Metallica, Slayer and Anthrax. Megadeth blend of speed, technical precision and aggressive lyrics has earned them a place among the genre most influential acts. Formed in the early 1980s by former Metallica guitarist Dave Mustaine, Megadeth carved out their own legacy becoming one of the most respected and successful thrash metal bands in history.
Formation: Dave Mustaine’s Vision
The origins of Megadeth are inextricably tied to Dave Mustaine departure from Metallica. In 1983 Mustaine was famously fired from Metallica due to conflicts within the band as well as his alcohol and drug abuse. Determined to prove himself and to create a band that could rival his former bandmates Mustaine channeled his anger and frustration into founding Megadeth.
He quickly recruited bassist David Ellefson, guitarist Greg Handevidt and drummer Dijon Carruthers forming the first version of Megadeth. However the lineup would go through several changes in its early years as Mustaine sought the right mix of musicians to bring his vision to life. By 1984 the core of the band solidified with Mustaine, Ellefson, guitarist Chris Poland and drummer Gar Samuelson.
Mustaine goal with Megadeth was to create faster, more aggressive music than anything Metallica had done. This desire for intensity and speed would become a defining characteristic of the band’s sound.
Killing Is My Business… And Business Is Good!
In 1985 Megadeth released their debut album “Killing Is My Business… And Business Is Good!”. The album was a raw and aggressive statement of intent full of lightning-fast guitar riffs, politically charged lyrics and Mustaine signature snarling vocals. Songs like “Mechanix” (a sped-up version of Metallica “The Four Horsemen”) and “Rattlehead” set the tone for Megadeth early work combining technical precision with an unrelenting sense of speed and fury.
Although the production quality was rough due to budget limitations “Killing Is My Business…” was well received in the underground metal scene and established Megadeth as a force to be reckoned with in the burgeoning thrash metal movement. The album also showcased Mustaine strong songwriting abilities, which were beginning to mature.
Peace Sells… But Who’s Buying?: The Breakthrough
Megadeth second album “Peace Sells… But Who’s Buying?” was released in 1986. It would go on to become a thrash metal classic and their breakout album. The album which was produced by Randy Burns and next remixed by Paul Lani. Had a more refined sound but kept the intensity of the original release.
The title track “Peace Sells” became one of Megadeth most iconic songs, with its rebellious lyrics and infectious bassline. It also became an anthem for the disillusioned youth of the 1980s addressing themes of government mistrust, war and social inequality. Songs like “Wake Up Dead” and “Devils Island” showed Mustaine skilled guitar technique and political criticism even more, solidifying his status as one of metal most important artists.
The critically praised song “Peace Sells… But Who’s Buying?” helped Megadeth break out of the underground thrash scene and achieve a larger following. The album popularity also cemented their place among the genre elite, among bands like Metallica, Slayer and Anthrax.
So Far, So Good… So What! and Lineup Changes
Following the success of “Peace Sells…” Megadeth internal struggles began to intensify. Mustaine ongoing battles with addiction, combined with tensions within the band, led to the departure of Poland and Samuelson. They were replaced by guitarist Jeff Young and drummer Chuck Behler for the band third album “So Far, So Good… So What!” released in 1988.

While the album continued Megadeth streak of success with tracks like “In My Darkest Hour” written in response to the death of Metallica bassist Cliff Burton. And “Set the World Afire” it also reflected the chaotic state of the band. The production was criticized for being uneven and the instability within the band made it difficult for them to reach the heights of their previous work. However “So Far, So Good… So What!” still solidified their place as thrash metal innovators.
