One of the greatest hip-hop records in recent years is getting a sequel this September although it won't be a traditional follow-up. Stones Throw will be releasing Madvillainy 2: The Box on September 15 with pre-orders available until August 15. The box set will be exclusively available on Stones Throw's web site.

Here's what $124.99 + shipping will get you:

CD Madvillainy “2” The Madlib Remix. 25 tracks. Read more below.
7-INCH “One Beer (Drunk Version)” Madlib's original 2004 version, lost until recently on the floor of his Bomb Shelter studio. If you saw the studio you'd understand.
CASSETTE The Madvillainy Demo Tape. 12 tracks, 36 minutes. This is the first and only official release of the infamous Madvillain demo that “leaked into cyberspace,” while the album was still in progress, as DOOM alludes to in the lyrics of “Rhinestone Cowboy.”
T-SHIRT Nominated. Best Rolled L's. Madvillain shirt.
COMIC BOOK Meanwhile... the continuation of the All Caps video, included with the CD.
THE BOX 12x13x3 inches. Wrapped in a silver like a mask.

Regarding the traditional sequel with all new material, here's what's stated on Stones Throw's site:

Yeah, we’re waiting for the new Madvillain too. Every once in a while we hear from DOOM, and he tells us he’s getting closer. Madlib still sends him beat CDs. DOOM always remembers our birthdays. But, we don’t have the sequel, and we know every nuance of Madvillainy. So we’ve been bumping this album while we’re patiently waiting. And it’s been good. Like visiting with a friend who you haven’t seen in years and remembering why you were friends to begin with.
