RJD2 has announced that he will be auctioning off five original beats via eBay, with each currently set at a bidding price of $150. All of the proceeds from the legendary Def Jux/MHz producer’s tracks will go directly to the charitable organization Doctors Without Borders. In addition, winners will own the Pro Tool session master recording and the master rights of their tracks.

Fans can check out snippets of each of RJD2’s beats via his SoundCloud. Artist looking to bid on the tracks can head to eBay to place their bids.
