On this day, April 4, in hip-hop history...

2009: Run-D.M.C. was inducted into the Rock and Roll Hall of Fame on April 4, 2009. Nominated in 2008, the Hollis, Queens trio became the second hip-hop act to be inducted into the organization after Grandmaster Flash and the Furious Five in 2007. Other inductees that year included Metallica, Jeff Beck, Little Anthony and the Imperials and Bobby Womack.

Run-D.M.C. is widely considered one of hip-hop's most influential and celebrated acts. The group is not only responsible for one of the earliest and most successful hip-hop/rock crossover hits with "Walk This Way," but it also changed the landscape of hip-hop in the early '80s, shifting the spotlight from the DJ to the emcee. Run-DMC released seven albums in its two-decade career, officially retiring the group in 2002 after the murder of DJ Jam Master Jay.
