What happened to the Pioneers of Hip-Hop??

Last time I looked, tonight's (3/18) show at Metro was called the "Pioneers of Hip-Hop" tour, featuring a great line-up of old skool icons. Here was the originally advertised bill: KRS-One Kool Moe Dee Melle Me Busy Bee Kool Herc Grandmaster Caz Temple of Hip-Hop Museum Mass Hysteria Longshot DJ Cooperpot Sape La Rock Rude One However, last night in the RFC mailbox, the weekly Metro news e-mail arrived and it listed a line-up and show name that was completely different!?! Reverse and EV Productions present Return of the Boom Bap with: KRS One Brand Nubian Masta Ace with Wordsmith Mass Hysteria Longshot Diverse and DJ's Copperpot, Sapien and Rude One, hosted by Profound. What happened to Melle Mel, Busy Bee, Kool Herc and the whole "Pioneers of Hip-Hop" theme? What the hell is The Boom Bap? Unfortunately, despite the siginificantly smaller bill, tickets are still a whopping 25 bucks at the door. Ouch! Nothing against the legendary KRS-One, but that's damn steep for a show at Metro...especially for a bill that's been chopped in half. We'll keep you posted if word comes in about why the "Pioneers" show got canceled. In the meantime, I'd recommend checking out the Fela Kuti DVD release party tonight at Sonotheque instead.
