The first cassette by Dusk To Dawn, a very under-rated early 90s German band mixing wave, goth, and synth... I first heard them on some compilations through Beton Tapes and was impressed, thus was quite thankful to finally get my hands on this couple years ago. You can find their second cassette at Crispy Nugget's blog [here]. You can also hear more material at their Soundcloud page here. I know one of the members went on to form Blues of A Lesser God, which uses the same melody from the track "Eternal Dawn" featured on this tape on their song "For Love & Rock'N'Roll". I saw some of the Blues From A Lesser God tapes posted on the blog EBM-Minimal Goth-Industrial recently. I haven't had the chance to listen to them yet, but do have the "Groove-T Music" tape in my collection and did not think it was anything nearly as strong as Dusk To Dawn (more electro-rock though... so not my personal favourite style). Still probably worth investigating if you are a fan and have the time...
Look for new reissue LP:
