The aspiring hip-hop producers who populate the forums at cratekings.com work together for mutual musical benefit — and not only by commenting on each other’s work and pushing the collective to tweak each sample, hone each beat, and better craft each instrumental track that they post. They also collaborate, as on the 14-track compilation of remixes of themes by Hollywood screen-music legend Henry Mancini. The set, Crate Kings vs. Henry Mancini, is available as a series of individual tracks (ZIP) or as a single mix, put together by Rafferty, one of the tribute’s contributors (MP3). Participants include Figment, DJ Oaty Love, DJ Tru Blu, Olivertone, Kid Konnect, Illstylus, Pyro. More info at cratekings.com.
