By now, Slaughterhouse fans are well acquainted with the fabled Glass House album, a Detox-esque project presumably sitting in somebodies vault. With alleged production from  Just BlazeAraabMuzik, J.U.S.T.I.C.E. League, Illmind, & Cardiak, the project certainly sounded like an upgrade from their mainstream studio debut Welcome To Our House. However, due to reasons that are mostly the product of unfounded speculation, the album seems destined to never see the light of day, despite Joe Budden's playful threats to leak it. 

Now, Royce Da 5'9" has hit up Grass Routes podcast for a lengthy interview, which led to the inevitable Slaughterhouse mention. Royce took it in stride, and actually dropped a little bit of optimism for all the eager fans:

"It's a work in progress," says Royce, speaking about their next move. "Everybody just passionate about it...It's never that we don't get alone with each other...Sometimes, you may have one member that wants to do it sooner than another member, and that causes a little bit of an issue, you know what I'm saying? But that's just passion. Passion for the creativity, and that's a great thing. It's a work in progress, and it will happen, it's just about when."

Royce goes on to reveal his ideal plans for rolling out a solo project, PRhyme, and Slaughterhouse. "It's only hard because people demand a timetable from me that I can't give them. That's it. But in terms of it getting done, it will get done."

Check out the full interview below for much more from Royce, including a little bit of Book Of Ryan info. If you can't listen, Royce describes the project as a look back at his history, and claims it's what his first album should have been.
