The year was 1989, and Derrick May was at a creative peak as both a DJ and producer. Under his Rhythim Is Rhythim moniker, he released a string of landmark records on Transmat, while his residency at Detroit's The Music Institute showcased the distinctive DJ style that would soon take him onto the international stage. Around the same time, he hosted a weekly radio show on Detroit radio station WJLB, alongside influential programs by The Electrifying Mojo and The Wizard (Jeff Mills).

For one of these broadcasts, May assembled a 15-minute megamix in his studio during the week leading up to the show. He opened his radio set with this continuous mix, blending his own tracks and versions into a seamless introduction that reflected his approach to DJing at the time. It includes unreleased versions of classics such as ‘Nude Photo 88’ and ‘Strings Of Life’.

‘All of this is unreleased because I made it as I was playing it on the spot as a special Mayday Mix for my show on the radio station WJLB in 1989, edited together straight from the keyboards live to tape. There is no other recording of these tracks in this form, only here’.

The original WJLB master tapes have since been lost, and no official recording is known to survive. Fortunately, many listeners recorded the broadcasts at home. One such cassette, preserved by Richie Hawtin, eventually made it our way. It has been carefully restored and mastered, with the artist’s approval.

To highlight this remarkable document of techno history, the recording is now available as a limited-edition, one-sided 12-inch release. The mix has been cut as a continuous side, visually divided into eight sections, while the reverse features a custom engraving.
