Smithsonian preparing for Hip-Hop exhibit

For nearly three decades, hip-hop relics such as vinyl records, turntables, microphones and boom boxes have collected dust in boxes and attics. On Tuesday, owners of such items, including pioneering hip-hop artists such as Afrika Bambaataa, DJ Kool Herc, Grandmaster Flash and Fab 5 Freddy, will blow that dust off and carry them to a Manhattan hotel to turn them over to National Museum of American History officials
