Despite being overplayed, Mill's purpose maker material is still, in my opinion, his best yet. Solid, funky, and beautifully crafted, the influence of these tracks on modern techno is undeniable. Launching the minimal/tribal sound thats still going strong today, they continue to act as a reference point for producers like Sims, Beyer, Mac etc.
If you have turntables, then seek out the vinyl releases. There's nothing better then dimming the lights, cranking up the volume, and rinsing a bit of purpose maker.
