When Just Blaze teased his personal collection of legendary unreleased music earlier this week, he said that such exclusives were limited to those lucky enough to be "night owls" only. Then, sadly enough, he deleted almost all of those teases while hinting that some of them "will end up somewhere soon." Stopping by Q-Tip's Beats 1 show Abstract Radio, Just did not disappoint:

Listeners were treated to a Robert Glasper-assisted version of Kanye West's Late Registration instaclassic "Touch the Sky," a Dipset remix in the form of "I Really Mean It," an alternate version of Usher's "Throwback," a new take on Rick Ross's "Lord Knows" verse, and that previously teased "Black Album version" of Jay Z's "Early This Morning." Just also ran through some of his confirmed classics, meaning the entire episode is a must-listen.
