Beats & Rhymes: Hip-Hop of the '90s, Vol. 2 picks up where its predecessor left off, running through a number of rap classics and underappreciated gems from the early '90s. Cut for cut, the 15-track Vol. 2 isn't as consistent as its predecessor, but there are still plenty of terrific moments on the disc -- including tracks by Leaders of the New School ("Case of the P.T.A."), A Tribe Called Quest ("Check the Rhyme"), Brand Nubian ("Slow Down"), Eric B. & Rakim ("What's On Your Mind"), DJ Jazzy Jeff & the Fresh Prince ("Summertime"), and the UMC's ("Blue Cheese") -- that make it an essential history lesson. That said, there's still no reason why there are no less than three Chubb Rock cuts on this disc.
