A set of vintage mixes have been made available to download to celebrate sci-fi techno genius Jeff Mills’ 50th (!) birthday this week.

The seven half-hour sets were taken from Mills’ WLJB Detroit radio show between 1986 and 1989, which he presented under his pseudonym The Wizard.

German blog Nerdcore, who kindly uploaded the mixes, reckon they were probably recorded straight to cassette – hence the slightly iffy audio quality. But don’t let a bit of tape hiss put you off techno (and funk and hip hop) this good. [via XLR8R]

Mills will join Robert Hood, Timeline and James Ruskin at the launch of this year’s series of The Hydra in London on 24 August.
