Double Dee and Steinski is a duo of hip hop producers, composed of Doug "Double Dee" DiFranco and Steven "Steinski" Stein. They achieved notoriety in the early 1980s for a series of underground hip-hop sample-based collages known as the "Lessons".
Although they never had a hit record, they proved highly influential for subsequent artists such as Coldcut, DJ Shadow, Cut Chemist, the Avalanches, and Girl Talk. Their music was not widely available on CD until 2008 due to their use of copyrighted material. There have been occasional illegal re-issues, and several internet sites have mp3s of their music available for download.
