What year was the hip hop group Run-DMC formed?

The hip-hop group Run-DMC was formed in 1983.

The group was created in Hollis, Queens, New York City, by Joseph "Run" Simmons, Darryl "D.M.C." McDaniels, and Jason "Jam Master Jay" Mizell. Simmons and McDaniels provided the rapping, while Mizell became one of hip-hop's most influential DJs and producers.

Run-DMC helped define the sound and image of 1980s hip-hop. Their stripped-down beats, forceful delivery, streetwear, and collaboration with rock musicians expanded rap's audience. The group was especially important in bringing hip-hop into mainstream radio, MTV, and major concert venues. Their 1986 album Raising Hell included the breakthrough crossover hit "Walk This Way," recorded with Aerosmith.

The year 1983 refers to the group's formation, not its debut album or breakthrough period. Their self-titled debut arrived in 1984, while Raising Hell followed in 1986. Run-DMC's classic lineup remained a trio until Jam Master Jay's death in 2002, after which the group largely stopped performing.
