Production is all-encompassing (beats, samples, et cetera). It takes a lot of talent to be a genuinely great producer (as with any sort of musical genre), which is sadly lost on ****-tards who dismiss rap as rubbish.
Organized Konfusion's Stress (The Extinction Agenda) (amazing jazz sampling with some of the best rapping EVER; solidified Pharoahe Monch as my all-time favorite rapper); Big L's Lifestylez ov da Poor and Dangerous (so macabre it's hilarious. Production is wanting but who cares with rapping this amazing); Jay-Z's The Blueprint (just cuz, I guess); GZA's Liquid Swords (not as engaging per se as the Wu-Tang debut, but this is more accessible, I think); The Coup's Steal This Album (Public Enemy has **** all on The Coup; the production is so much better, and the lyrics and delivery aren't as preachy and annoying); UGK's Ridin' Dirty (great rapping with unbelievable production; basically the blueprint for southern rap, excepting infinitely better than nearly all records that followed. You in particular would dig the production for this, I'm sure)
My Spanish teacher is all happy-go-lucky-kindergarden-fun-time and my old german teacher was as boring as a tree stump. She did let me sleep though, which was pretty cool. So was my Pre-Algebra teacher, but she yelled at me if I put my head down. -_-
Some teachers are way past the age to retire. I wonder why they won't, sometimes.
