Before ska punk began, many ska bands and punk rock bands performed on the same bills together and performed to the same audiences. Some music groups from the late 1970s and early 1980s, such as the Clash, the Deadbeats, the Specials, the Beat, and Madness fused characteristics of punk rock and ska, but many of these were either punk bands playing an occasional ska-flavored song, or are usually considered 2-Tone ska bands who played faster songs with a punk attitude. During the late 1980s and early 1990s, ska-punk enjoyed its greatest success, heralded by bands such as Fishbone, Dance Hall Crashers, The Mighty Mighty Bosstones, Citizen Fish, Sublime, the Porkers, Mad Caddies, Culture Shock, Operation Ivy, Less Than Jake, and Reel Big Fish.
