It is very likely that you have heard of RJD2 (born Ramble John Krohn) and haven’t even realized it yet. The DJ/producer has been making music since the mid-nineties when he was the background DJ for the Columbus, OH, rap group MHz. His name comes from a friend’s shout-out on a rap track that stuck with him. He later released a solo “mix CD” titled Your Face and Your Kneecaps under the Fondle ‘Em record label. A year later, he signed onto Definitive Jux, the record label operated by renowned DJ El-P, and released two highly acclaimed solo records Deadringer and Since We Last Spoke. During his time on Definitive Jux, he worked with fellow Columbus MC, Blueprint, and released two albums under the collaborative title Soul Position, the second of which was released under the Rhymesayers label. He continued to work with underground rappers producing beats for Cunninlynguists, Cage, MFDoom, Diverse, Aceyalone, and also producing a cover of Radiohead’s “Airbag,” for the album Exit Music. He released his third solo album, The Third Hand, after leaving Rhymesayers for the XL Recordings label, citing an interest in making music that was more “pop-friendly.” In 2009, he left XL Recordings to create his own record label, Electrical Connections, which is expected to release his first fully independent album, The Colossus, sometime next year.
