Heavy Metal legend Dave Mustaine has announced that his band Megadeth will be releasing their final album in 2026 and embarking on a farewell tour. The band is renowned for dynamic levels of instrumental proficiency and impressive longevity, consistently releasing music over a 40+ year run.
While not exactly a household name to non-metal fans, Megadeth is an undeniable staple of the metal scene. Their explosive, fast-paced sound rocked the genre to its core.
Through numerous lineup changes over the years, its frontman and founder, Mustaine, has remained the face of the band. To understand the story of Megadeth is to understand the story of Mustaine — one of metal’s most beloved guitar virtuosos.
Off to a Rough Start
Megadeth’s journey began where most stories would end. In 1983, Mustaine was kicked out of what would go on to become the most successful metal band of all time: Metallica.
This is perhaps the most famous — and most disputed — piece of drama in metal history. Numerous versions of the story exist, but most sources, such as LoudWire, agree it involved a deteriorating relationship and occasional physical altercations.
The conclusion, however, is generally agreed upon: in 1983, right before the recording of Metallica’s smash-hit first album (which Mustaine co-wrote), the band woke Mustaine, told him he was fired, and gave him a bus ticket home to L.A according to Ultimate Classic Rock.
Metal folklore states that it was on that bus ride that an infuriated Mustaine scribbled down what would become Megadeth’s first lyrics.
Things didn’t work out for Mustaine immediately after the breakup. He played in a short-lived, unsuccessful band called Fallen Angels. Ironically, Mustaine’s next successful band would come from one of the very things that got him kicked out of Metallica: an altercation.
The Beginning of Megadeth
One day in 1983, a hungover Mustaine shouted at his downstairs neighbor to stop playing their instruments too loudly. After an initial back-and-forth, Mustaine befriended his musician neighbor David Ellefson.
The two began playing together, and Mustaine renamed Fallen Angels to Megadeth. For the first couple of years, the band went through several lineup changes, with Mustaine and Ellefson remaining the only consistent members.
During the early 80s, the band started to gain momentum and began touring in the burgeoning thrash metal scene, in which they were seen as pioneers. In a genre known for lightning-quick guitars, Megadeth stood out for its impressive musicianship and explosive guitar solos.
Early Success
In 1985, after years of touring, Megadeth released their first album, Killing Is Business… and Business Is Good! While not their most famous release, the album featured several early thrash classics like its title track and “The Mechanix.”
The album is also notable for introducing the band’s skeleton mascot, Vic Rattlehead — depicted with his eyes, ears, and mouth clamped shut by various devices, meant to personify the phrase “see no evil, hear no evil”.
By the mid-80s, things were going very well commercially. Their second album, Peace Sells… but Who’s Buying?, saw the band break into the Billboard charts. The album helped solidify their name in the metal world and even began to edge them into a space metal bands rarely go: the mainstream.
Their third album also found Billboard success and continued the streak — but it wouldn’t hold a candle to what was coming next.
Rust in Peace and Cultural Peak
It is difficult to overstate the importance of Megadeth’s 1990 album Rust in Peace. Often considered one of the greatest metal albums of all time, this hit-packed release saw Megadeth push their already impressive musicianship to its limits.
Most notable among the tracks is the legendary “Holy Wars… The Punishment Due.” The six-minute epic is known for sounding like several songs mashed into one — often shifting dramatically in tone and tempo, coming off as a sort of metal “Bohemian Rhapsody.”
The guitar work has also become the stuff of legend. From the opening riff to the various solos, the song is iconic. A popular fan joke was that Dave Mustaine wrote the five best guitar solos of all time — then decided to cram them all into one song.
While Rust in Peace marks the band’s clear peak, it was by no means the end. Megadeth continued to release critically and commercially successful albums throughout the 90s. Most notable was Countdown to Extinction, which featured the band’s most successful single: “Symphony of Destruction.”
Later Years
In the 2000s, Dave Mustaine temporarily lost the ability to play guitar due to a hand injury, and Megadeth was briefly disbanded. During this time, Mustaine entered a rehab program and became sober after a lifelong battle with addiction.
Following his recovery, Mustaine returned to the stage and began regularly releasing new music, even experimenting with genres like pop.
Throughout the 2010s and 2020s, Megadeth continued to tour consistently, becoming a staple of metal tours worldwide. The band came to be seen as part of the “old guard,” playing alongside — and helping usher in — a new generation of metal artists.
Rivalry with Metallica
Megadeth’s legacy is one of the richest in metal history, but the band’s story is undeniably linked to what many see as its more popular older brother: Metallica.
While instrumentally similar, one key difference between the two bands is the man behind the mic. Mustaine is known for his unique raspy singing voice, often compared to a snarl. This non-traditional style gives him a more menacing, aggressive tone found within more extreme metal.
Metallica, while still intense, is known for its cleaner, rock-and-roll-inspired vocals. This more radio-friendly sound has resulted in Metallica being seen as a more “accessible” metal band than most. Megadeth, in turn, is seen as a version of Metallica that appeals to more hardcore fans.
The rivalry between the two extends beyond fan comparison. Mustaine has publicly claimed on numerous occasions that he was not given credit for co-writing many of Metallica’s early songs, according to GuitarPlayer.com. In some cases, he released his own versions of these songs under Megadeth.
The rivalry eventually softened, with Mustaine publicly reconciling with Metallica’s members in later years. In 2011, he even performed a concert with them, focused on the early hits they used to play together.
Retirement
As of now, Megadeth is still at work on their final album, set for release in 2026. The project has not yet been titled and will be accompanied by a farewell tour. The band’s YouTube channel released a video featuring Rattlehead “warning” viewers about the upcoming tour, framed as an explosive event.
In a public statement announcing his retirement, Mustaine urged fans not to mourn the band but to celebrate how much they had accomplished.
“We started a musical style, we started a revolution, we changed the guitar world and how it’s played, and we changed the world. The bands I played in have influenced the world. I love you all for it. Thank you for everything,” said the rockstar in his statement.
For many fans, Megadeth has been touring longer than they have been alive. In a nearly 40-year run, the band has released 16 albums and helped reshape the metal genre as a whole. Trying (and often failing) to learn “Holy Wars” is a universal memory shared by countless burgeoning guitarists.
As the band prepares for its final moments on stage, they will undeniably leave behind a lasting legacy on the genre. Rock on.
