JS-1 recently unveiled a project that has been in the works for nearly two years now, painstakingly collecting 3 hours worth of demo and obscure / rare tracks. Because the majority of this tape are demos, the quality isn't as clean as a standard release mixtape. Lots of these gems were pulled off cassette tapes, overdubs and radio rips. The KRS-ONE x DJ Premier track that was left on the cutting room floor during the recording of Return of the Boom-Bap alone is worth downloading this tape. More info can be found over at JS-1's spot.
