BIZ AND THE REST:

Watch Justin Timberlake and Jimmy Fallon's "History of Rap Part 2" With the Roots (Pitchfork, 7/20/11)

If anything, the sequel moves even faster. In about five minutes, Fallon and Timberlake did chunks of songs from Kurtis Blow, Grandmaster Flash and the Furious Five, N.W.A, Public Enemy, Rob Base and DJ E-Z Rock, Salt-N-Pepa, Vanilla Ice, Black Sheep, Cypress Hill, DJ Kool, DMX, Nelly, 50 Cent, OutKast, Lil Wayne, DJ Khaled, Cali Swag District, and Rick Ross, and lead the crowd in a massive singalong to Biz Markie's "Just a Friend". It's an impressive performance indeed; the combination of memorization, dancing, and comic timing damn near boggles the mind. Watch it below.
