I've talked about it before but Attention K-Mart Shoppers is such an incredible thing, a collection of overhead department store music from a forgotten era https://archive.org/details/attentionkmartshoppers
My favorite thing is still the opening track from the October 1989 tape. The synths! The distortion! The yearning calls of the instruments! The piano! https://archive.org/details/KmartOctober1989
There are so many good tapes though

@cwebber Big fan of #StereoSampler records myself, its a perfect intersection of new technology; progressive engineering and musicians who were used to working lots of gigs.
Decca and RCA Camden are the better labels for that type Im describing.
Track B3 from this innocuous one may be the best Beetles cover ever:
