By day, Dori Hadar works as a criminal investigator. But he moonlights as a DJ and prowls for interesting LPs. Sifting through crates of old soul and funk, he found a box of records that mystified him. The sleeves were painted by hand — and the “records” inside were made of cardboard. Hadar put his detective skills to work to find the man who called himself Mingering Mike. Produced by Derek John.
