As we have reported several times now, The Roots will drop their latest album, Undun, next Tuesday, Dec. 6. It serves as the band's thirteen album to date and their first concept album. It's kind of crazy to think it took them this long to go this route, though that's not to say concepts haven't worked their way into many of their tracks on their previous albums. Hell, most of their more recent material has been much more narrative-based and their previous record, How I Got Over, was loosely based on a dark/light idea. But Undun dives headfirst into a story and stays with it from start to finish. You can hear it at NPR.
