Toto XX: 1977-1997 is hardly the definitive collection that its title suggests. Essentially, this is a Toto reunion album, featuring nine new studio cuts and four live tracks, including a version of "Africa." The band sounds better than you might expect, but the material isn't all that different from that on Tambu -- the performances are a little tighter, slicker and better. That said, it's not particularly interesting to anyone except hardcore fans, who will probably be pleased to hear an approximation of the original lineup back in action, regardless if the tunes are memorable or not.
