I know at least one person is enjoying these, so here's Round 3. For some reason, I happen to be posting 5 albums by MC duos (and also Jeru down there at the end).
Artifacts - Between A Rock And A Hard Place (1994)
This has to be one of my favorite albums of all time. Great production by Buckwild and T-Ray, and Tame-One and El Da Sensei are sick as hell (particularly Tame). Definitely check out their second album, That's Them (1997).
Da King & I - Contemporary Jeep Music (1993)
Okay I'm gonna so far as to say this is probably the most underrated hip-hop album of all time, simply because it's extremely good on all fronts and nobody talks about it, 'ceptin for on this fabulous internet of ours I suppose. Coincidentally, as my brother once pointed out to me, this also has to be the lamest name for a hip-hop group of all time.
Das EFX - Hold It Down (1995)
Diggy Das' third album gets less love than the first two, and I slept on it for a while, but it's gotta be best. Great production by Easy Mo Bee, and Drayz and Books rip up the mic as usual.
Organized Konfusion - Organized Konfusion (1991)
You could pretty much go either way with this or their second album, Stress: The Extinction Agenda (1994), but it doesn't matter because both of them prove that Pharoahe Monch is the BEST MC OF ALL TIME. In recent years Monch has been wasting his talent by singing like quasi-R&B crap with a backing band, but don't be fooled. The dude is unbelievable. The beats here are nothing special, but Monch and Prince Po are the best rhyming duo ever recorded.
Heltah Skeltah - Nocturnal (1996)
More classic Boot Camp Clik. Ruck (Sean Price) and Rock (Rockness Monsta) are probably the best MCs in BCC, which is saying quite a bit. Just look at those little guys hanging upside down. Love it.
Jeru The Damaja - The Run Rises In The East (1994)
All I really can say is that Jeru is the man. DJ Premier produced the entire album (as with Wrath of the Math, 1996), and it's probably his finest work.
