Sandy is spinning a set, not just a set, but A set, as in only artists beginning with the letter “A”. Abba, Alphaville, Alice Cooper, Arcadia, etc.
She spins the Art of Noise, and I says, “cool vinyl Sandy, you spinning cutting edge old school!” and then I go, “ooh, that’s a good phrase, ‘cutting edge old school!'”.
That’s what this is: cool, new obscure music that’s been around forever.
