My friend Toby Warner tipped me off on one of the coolest mixtape sites I've seen in some time. The Nice & Slo mix from Mastermix is amazing-- 46 tracks in 11 minutes. Just as the Psychonauts encapsulated the mid-nineties Mo'Wax sound with their Time Machine mix, this mix documents mid-eighties electro, funk, breaks and hip-hop. Direct download from here.
