Cro-Mags, 1 March 2023

The Cro-Mags are an American hardcore punk turned crossover thrash band from New York City. The band, which had a strong cult following, has released five studio albums, their first two considered the most influential. With a Hare Krishna background, they were among the first bands to fuse hardcore punk with thrash metal and were associated with the birth of a tougher attitude within the hardcore scene in the late 1980s, related to the world of martial arts. John Joseph McGowan and Harley Flanagan (formerly drummer for The Stimulators), are practitioners of boxing and Brazilian Jiu-Jitsu respectively. The Cro-Mags have gone through several line-up changes, and as of 2016, there are no constant members left in the band.
According to AllMusic, "before the Cro-Mags, the idea of combining heavy metal and hardcore together was unheard of. But with the release of their classic debut, The Age of Quarrel, hardcore-metal was born, and in its wake came a legion of similarly styled offspring (Biohazard, Vision of Disorder, etc.)."
