Game-changers Serato and their Whitelabel.net music label have given a fitting tribute to DJ A-Trak, gifting him the very first run of custom picture disks on their label. The innovative concept has a dual purpose, the Dust La Rock-designed “Mr. A” graphical side plays Say Whoa while the other side serves as a Serato control disk. The disk was based on DJ A-Trak’s album with Nike+, Running Man: Nike+ Original Run which dropped back in late August of 2008. 1,000 promotional disk I keep trying to tell you all that we ae more than just dj's.
