The genesis of heavy metal as a music genre took place during the 1960s and 1970s, characterized by bands pushing the boundaries of sound through distortion and intensity. As the ’70s progressed, the thrash metal subgenre began to carve its own identity, emerging prominently in the early 1980s. This evolution was significantly influenced by the innovative drumming styles of bands from the New Wave of British Heavy Metal, particularly Mötorhead, combined with the fierce energy of the burgeoning hardcore punk scene.
In 1981, the foundations of thrash metal’s “Big Four”were laid with the formation of Anthrax, Metallica, Megadeth, and Slayer. This year also marked the first usage of the term “thrash metal”in Kerrang! magazine. Over the years, thrash has blossomed into a diverse array of bands and styles, with a multitude of groups embodying the hardcore essence that rivals even the Big Four.

Initially rooted in melodic death metal and metalcore, Shadows Fall transitioned to a sound influenced by thrash and power metal following their 2000 album, Of One Blood. This shift occurred after they faced criticism for sounding overly similar to Sweden’s melodic death metal scene. Their 2002 release, The Art of Balance, was well-received, despite an unexpected choice to conclude the album with a cover of Pink Floyd’s “Welcome to the Machine.”
Unfortunately, the band disbanded after their 2012 album, Fire from the Sky, following lineup changes and a farewell tour. However, Shadows Fall reunited in 2021 for a performance in Worcester, near Boston, and made their return to the studio with a new single titled “In the Grey,”released in December 2024.

Death Angel, stemming from the Bay Area thrash scene, just narrowly missed inclusion in the Big Four due to a timing mishap. Throughout the ’80s, they toured extensively, often supporting Metallica. However, a devastating bus accident in 1990 led to significant injuries for drummer Andy Galeon and a temporary halt to their momentum, resulting in their eventual split in 1991. Thankfully, after reuniting for a benefit show in 2001, the band returned to the studio in 2004, showcasing their resilience in the metal scene.

Exodus is one of the pioneering Bay Area thrash bands, and notably, guitarist Kirk Hammett started with them before joining Metallica in 1983. Despite tumultuous lineup changes over the decades, with only drummer Tom Hunting enduring as the original member since 2007, Exodus has remained influential in the thrash genre. Many metal critics believe Exodus deserves to be considered as part of the Big Five rather than the Big Four.
Their latest studio album, Persona Non Grata (2021), has proved that the enduring legacy of Exodus continues unscathed by time.

Critically acclaimed for their contributions, especially the groundbreaking album Roots, Sepultura features indigenous elements in their work, adding depth to the thrash genre, making them a staple in heavy metal history. Notably praised by AllMusic’s Eduardo Rivadavia as “perhaps the most important heavy metal band of the 90s,”their influence is undeniable.

Testament stands apart from the Big Four, continuously influencing emerging metal bands while maintaining their signature shredding power even after four decades.
Now under Nuclear Blast, Testament is working on their highly anticipated fourteenth studio album, expected to debut in 2025. This underscores their ongoing relevance and ability to evolve within the genre.
