We Rave You reports an auction containing a Moby DJ demo cassette dated to 1987–88 and a Depeche Mode tape associated with material that later appeared on Ultra. The sale brings physical traces of those earlier periods into view.
Their cultural interest lies in the distance between a working recording and a widely released version. Tapes preserve a way of circulating music before immediate file-sharing became routine. Provenance, availability and individual lot details should be checked against the seller's current listings.
