The Third Wave of Ska Revival emerged in the late '80s, when certain members of the American punk underground began returning to the sounds of British ska revival and infusing it with a hardcore punk attack. During the early '80s, this third wave continued to grow -- more bands continued to pop up across the country, but many of the most popular were based in California. As time wore on, the hardcore influences eventually mutated into heavy metal, much like hardcore punk itself. Eventually, the third wave of ska revivalists broke into the American mainstream, thanks to the success of fellow Californian punk revivalists Green Day and the Offspring.
