Here's a rare cassette release by a band from the Netherlands called Das Ding, one of many in a line of fantastic European minimal synth bands. Not a ton of information to be gathered about these guys, but the cassette is one of three releases, their first appearing in 1982 and the final in 1985.
1. Oradour Sur Glane 2. Sad But True 3. Parental Malpractice 4. H.S.T.A. 5. Jazz 6. Reassurance Ritual
