DJ Scratch has been instrumental in hip hop for more than 25 years, first as the guy who won damn near every turntable competition he entered and later as the unofficial third member of pioneering hip hop group EPMD and producer of classic tracks by Busta Rhymes, LL Cool J and others.

For the latest episode of Crate Diggers, Scratch walks us through some gems in his collection, including an original test pressing of LL Cool J “I Need a Beat,” an ultra-rare soul song released by Budweiser in 1972 and the plate used by Run-D.M.C. to record the original version of Beastie Boys’ “Slow and Low.”

We also get to see the man behind ScratchVision discuss EPMD’s original skepticism upon working with him and the story of the broken table that led to the most inadvertent greatest DJ set ever (spoiler: It involves “nuts on the cross-fader.”)

Scratch may be the only person in history to have rare Michael Jackson acetates and separate his vinyl between “bloods” (red records) and “crips” (blue records). Check it.
