On The First, the drums are an 8 bar loop and the way the producer, Hiroshima (never to be hear from again) made the kicks bounce on bar 6 and then how they snapped the snares over the rapid kicks throughout bar 8 just suck me in. hands down my favorite drums on any hip hop song.
On I Really Mean It, Just Blaze just really took the idea of drum programming and turned it on it's head. I mean, I could be wrong about the originator but there was stuff on there * I * never heard previously. Just the over use (but not) of cymbals, how he had tom rolls rolling into snare rolls that he programmed, and then he had sample drums rolls and fills from marching bands that he would drop in to fill the end of a bar.
