of the albums put out post death, rusd is the most og-like, and sir is probably next.
albums completed when pac was free (all of his albums except matw and some of makaveli) reflect his own creativity, and although some songs were enhanced and rearranged, in the end it was likely under his approval.
in the process of creating music, usually a very simple base beat is made to which artists record their verses. it is after the vocals are recorded that the beat is elaborated upon and built into a polished and finished product. this is what people fail to realize about many og's - that they reflect a snapshot in the life span of a song and not necessairly how pac or anyone else intended the final product to look or sound.
