My favorite Fleetwood Mac album would have to be without a shadow of a doubt - Tusk. The 2004 deluxe version of the album is an excellent version of Tusk because it contains roughs, outtakes and demos on disc 2 which were previously unissued. I always saw Rumors as a great album but considered Tusk to be a more creative success than its predecessor. That doesn't mean to say that i don't think Rumors wasn't very creative but that Tusk was a further advancement in Fleetwood Mac's ever-expanding style of music.
