Supposedly produced by label founder Larry Sherman in 1987 according to the Discogs entry, the tape kicks off side A with a ten minute megamix which I’d say was of UK origin by the use of spoken word samples and scratches, maybe Double Trouble who did lots of mixes for compilations round this time. No track list for this but it includes 'Hey Rocky!', 'No Way Back' and more.
Next up we have approx one minute snippets of forthcoming releases with a spoken word intro to each and here’s where the fun starts. The Discogs entry has simply copied the track list from the tape inlay but several listed titles don’t feature, some are by different artists and a couple aren’t listed at all. You can see from my photo that the previous owner had scribbled out the corrections as they listened to it. The tape plays a bit faster than most of the recordings released
