haven't been a huge fan of anything other than below the heavens.
it seems most feel the same other than stans
This. I really want to like his other stuff more, but between the awful mixes, goofy production choices (sometimes), and being all over the place, it's hard.
Below The Heavens is an amazing album. But also asking why he can't become mainstream in 2014 seems a little backwards. I'd almost ask how COULD he get mainstream now? It would be like someone like Nas blowing up now. I realize we have Kendrick, but there's only room for so many cats like that for the general public to accept, sadly. Kendrick also has the backing by Dre and a lot of melodic hooks, etc.
I'd love to see Blu do well. I enjoyed his last double album a lot actually. But I don't think he'll ever be a mainstream type of dude.
