In popular music, the term crossover (together with the more appropriate crossover rock) was used in the 1980's to describe a style of aggressive rock and roll. Bands who appreciated the fast hardcore punk stylings of bands like Minor Threat and Negative Approach, and equally appreciated the fast heavy metal stylings of Slayer and Metallica, began combining elements of both styles for a new musical style that became generally known as crossover thrash but is sometimes called punk metal. The first notable band of this style was New York City's Stormtroopers Of Death. The two hotbeds of the style were located in New York City and Southern California, home to Suicidal Tendencies. Other notable bands of the era were the Crumbsuckers, Hirax, Leeway, Cryptic Slaughter, The Cro-Mags, Method Of Destruction, and Dirty Rotten Imbeciles (aka DRI).
