This is an outstanding compilation. Pink Floyd is of course an "album" oriented band, but they manage to pull off the "best of" title with the tracks delivered here. My only complaints are that "Echoes" isn't the complete 23 minute version, instead we get a 16 minute edition. It's too bad the band didn't find a way to include that entire song, as it is probably their best ever, and is after all, the song the cd itself is named for. I think some of the other tunes are edited as well, though i'm not sure. Also, where in the world is "Run Like Hell"??!! One of their most popular and biggest hits is mysteriously absent. Other than that, this is one of the better albums you'll see this year.
