What was LL Cool J’s 1985 debut studio album?

LL Cool J’s 1985 debut studio album was Radio.

Released by Def Jam Recordings on November 18, 1985, Radio was produced largely by Rick Rubin and became one of the label’s defining early releases. Its stripped-down beats and forceful delivery helped establish LL Cool J as one of hip hop’s first major solo stars.

The album included “I Can’t Live Without My Radio” and “Rock the Bells,” songs that showcased LL Cool J’s commanding performance style. Radio was certified platinum by the Recording Industry Association of America and is often cited as a landmark of 1980s hip hop.

Listeners sometimes confuse Radio with Bigger and Deffer, LL Cool J’s second album, released in 1987. Radio is the debut, while Mama Said Knock You Out is his fourth studio album, released in 1990.
