Tanasia from Nas Lost Tapes 2 is probably around over a decade old like you said, that is one of the last I heard from him that I actually liked and sounded like old Rza. When he went Digital he lost it IMO, never was himself again.RZA seems like a perfect example of someone who is creatively stuck because he's trying to do too many things he's not really good at. His move to live instrumentation was largely predicated on him being upset about sample clearances and publishing percentages. The talent and ear isn't there to make it work, and he fell off a cliff the minute he started doing that shyt.
I'm not sure I've heard a great RZA beat in the last decade. Any track released then that sounded good was almost certainly recorded a long time ago.
