The Cro-Mags are an American hardcore punk / crossover thrash band from New York City. The band, which has 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. Harley Flanagan and John Joseph are practitioners of Brazilian jiu-jitsu and boxing respectively. The Cro-Mags have gone through several line-up changes and, as of 2018, there are no constant members left in the band.
