Converge is a 4-piece American band, formed in February of 1990 in Salem, Massachusetts, United States. Playing a blend of extreme metal and hardcore punk, this pioneer outfit helped define a lot of the rudiments of the fast-burgeoning metalcore and mathcore genres.
They first started by playing covers of hardcore, punk and heavy metal songs, being self-confessed "hardcore kids with leftover Slayer riffs". The band soon graduated to playing live performances in 1991 after recording some demos on a 4-track recorder. Read more on Last.fm
