More than three decades after the breakup of the Beatles, Paul McCartney is still -- with some degree of prudence -- pigeonholed as that band's most pop-driven member. Well, if that perception wasn't altered by his forays into classical music, it will certainly get a jolt from this compelling but decidedly odd disc, which was -- shades of Yoko Ono! -- initially composed as the aural component to an art exhibit in Liverpool. Combining '60s-rooted cut-and-paste techniques with state-of-the-art technology, McCartney (with some help from Welsh alterna-rockers Super Furry Animals) has crafted a piece that's anything but "pop." While it's certainly interesting to hear Macca deconstruct snippets of Beatle music, layering semi-recognizable riffs with spoken word, bits of found sound, and the like, the five-part Collage doesn't hold together -- either conceptually or sonically -- well enough to merit repeated listenings. Committed McCartney followers -- at least more open-minded ones -- will be more likely to take the time to decipher what's going on in "Peter Blake 2000" and "Real Gone Dub Made in the Manifest of the Eternal Now." But if your fandom doesn't stretch too far past the songs that appear on Beatles 1, head for another disc.
