During the '80s, as hip hop moved towards mainstream audiences, more record labels emerged. New labels were vying for the chance to sign new artists and steal established artists from labels like Sugar Hill. There were a number of new indie rap labels, but during this time the hip hop giant Def Jam also emerged.
Some new/influential labels include:
Def Jam records was founded in 1984 by Russell Simmons and Rick Rubin. The two quickly procured a distributing relationship with Columbia, cementing their place in hip-hop culture. Def Jam soon became a cornerstone for rap labels. Simmons also had a mangement company (managing Kurtis Blow, Run D.M.C. and others). At the end of the '80s Simmons and Rubin split. Simmons assumed control of Def Jam (hip hop only) and Rubin started Def American Recordings (rock and rap).

You can do a search of the library's catalog to see all of the LPs we have on a given label.
"12/33" is the call number we use to indicate that something is a record, and "DefJam" indicates the record label!
