Fleetwood Mac is reuniting for the Greatest Hits Unleashed North American tour. In conjunction with the tour, the band is releasing a greatest hits package, "Unleashed," and re-releasing, as a special CD/DVD box set, its diamond-certified CD "Rumours."

This is the first time the group is touring without support of a new album. Fleetwood said his band is certainly addressing the concept of writing new material. It would be Fleetwood Mac's first new collection of songs since 2003's "Say You Will."
