Cro-Mags

Cro-Mags are an American hardcore punk band from New York City. 

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.

the Cro-Mags helped define the East Coast hardcore movement with their now legendary debut, Age of Quarrel, loaded with hardcore classics like 'World Peace,' 'We Gotta Know,' and 'Street Justice'. 

The video for "We Gotta Know" received airplay on MTV at the time (during their alternative music show 120 Minutes and later on Headbangers Ball) and was one of the first-ever clips on MTV to feature slam dancing and crowd surfing.
