Brilliant idea, but it's not really music, and it's certainly not something your average hip-hop head will be able to handle. It's a line in the sand that very few will be able to cross. But at least there's a band out there that's willing to draw those lines and proceed alone if no one steps forward to follow them. After all, in above-ground hip-hop these days, what passes for experimentation is Jay-Z stringing about four worthwhile songs over two separate discs, as he does on The Blueprint 2: The Gift & the Curse. (The skills Jay-Z showed on 2001's The Blueprint and Unplugged discs now look like an aberration instead of an absolute fact.)
