For this unfamiliar, Blakroc was a rock/hip-hop crossover project between The Black Keys and Dame Dash and featured guest appearances from the likes of Mos Def, Pharoahe Monch, Jim Jones, Raekwon, RZA, etc...my understanding is their were some behind the scenes issues eventually and low sales which resulted in nothing more coming from the idea but hypothetically if the Keys were to do a Blakroc 2 without Dame but still the basic hip-hop/rock crossover in tact what rappers/MC's would you like to hear on there? guys like Curren$y, Gibbs, Denzel Curry, Kendrick come to mind instantly for me
