Side A contains the original SID music from from Noelle composed for the Commodore 64 version, plus a couple of tracks that were composed for the game but never actually used. As well as the dual-SID version that was also never used.
Side B contains most of the same songs but re-imagined by Anders Enger Jensen, which are a total treat to listen to. These songs were also destined for the Sega-CD version of the game that has since been cancelled.
If you collect Vinyl and video games, then this is the perfect synergy for your collection!
