“Gem Drops” is a rich, varied compilation covering “experimental electronic hip-hop inspired” music, with artists such as Anenon, yuk., Juj, Devonwho, Shigeto, and Sumsun. The 21 tracks were selected by curator Aaron Meola. It’s the sixth release from the collective Dropping Gems, and 100% of revenue will go to the American Cancer Society. Pay what you want for the download; a “very limited” run of handmade CDs with artwork will go to people who donate US $15 or more. I spoke with Kris Geffen, aka citymouth [SoundCloud page], about the release they put together to find out more.
