39 years ago today, LL Cool J released his platinum debut studio album, “Radio,” on November 18, 1985 via Def Jam Recordings and Columbia Records.

Produced by Rick Rubin, “Radio” became a Billboard chart hit and sold over 500,000 copies within its first five months of release. By 1989, it had been certified platinum by the Recording Industry Association of America for sales surpassing one million copies in the United States.

The project belonged to a pivotal moment in Hip-Hop’s culture and history, reflecting the new school and ghettoblaster subculture in the United States during the mid-1980s.
