Third Man Records' Jay Z Re-Release Contains Hidden Record

Jay Z's 2013 album Magna Carta Holy Grail was recently re-released on vinyl by Jack White's Third Man Records -- and as you well know, they've never been known to skimp on packaging or on innovative ways to re-imagine the functionality of a vinyl record. We'll let them explain what special treat they've added to the reissue, which is pressed on two 180-gram LPs and has a printed lyric insert:

Most exciting about this double LP is certainly the concealed postcard flexi disc hidden within the back cover and only accessible to those willing to take a knife to the iconic packaging. Once freed of its casing, this flexi disc plays a super secret hidden track.

That's right: a record containing a bonus track is contained within the the record's back cover. The record is currently available for order from Third Man Records, although there's no word yet on the nature of the mystery bonus track. Check out a teaser video for the release below:
