That's understandable, but your sound can still progress while still working with people from your past, I mean, it's not like Tech has to have an album full of Tekneko & RonnZ tracks, but is 1 each seriously that much of the "Same" while leaving the rest to new people? Hell, if he doesn't want more of the "Same", then why does he have (what was it) 8 tracks from Seven? Why must the "Same" concept apply only to each album, why not tracks... have a new/different producer on each song?
Sorry... I can be a little technical & argumentive at times :\
Either way, Tech is gonna do exactly what he wants/wanted to do and if that encludes not having those cats on there, then so be it, not like it's really gonna make or break the album.
