A very bizarre dubplate given to me by a dj friend who found this at Dr. Freeclouds Record Shoppe some many years ago. It features four tracks that can be found on other releases with semi-mediocre (very loud) mastering. Dancing in the rain on A1 sounds a bit muddy or blown out, but this could just be a product of wear on the plate. A2 has a version of Rainbow Islands that is much faster than the version on the original LP. Your Mine on side B1 appears to be the mixed version that is SPECIFICALLY on Happy 2b Hardcore Chapter 2, starting right on the first breakdown into the chorus, and begins mixing out to 'cloudy daze' at the very end of the track. B2 is a surprisingly unfinished version of 'Ooh Massive'.
There is no other identifying information about who individually or what company manufactured the dubplate, but now I own it and it is weird.
