Released 10 years apart, McCartney and McCartney II are the first two post-Beatles albums to be credited solely to Paul McCartney, without Wings or Linda McCartney. In that respect, it makes some sense to reissue the two simultaneously, but their original contexts could hardly be more different. In 1970, when advance copies of McCartney were sent to journalists, they included a press sheet announcing Paul's departure from the Beatles, which had the further effect of breaking up the band. McCartney was released a month before Let It Be, and it contained a fair amount of music that had been kicking around for some time. McCartney II, on the other hand, was released in 1980, about a year before the breakup of Wings, a band that was never much more than a vehicle for McCartney's solo songwriting efforts.
Wings had no John Lennon to play foil to McCartney. Lennon and McCartney, as everyone knows, were the songwriting partners who made the Beatles such a titanic force in the 1960s. By the time the band broke up, however, the partnership had been mostly dissolved for years. The two were almost always writing separately, and on those late Beatles albums, you can hear their personalities pulling apart. The separation is complete on the solo albums the two former Beatles released in 1970. Lennon's Plastic Ono Band is rough, nasty, self-absorbed, not a little narcissistic, and devoted to laying bare the rawest of emotions and memories. It has overshadowed McCartney since its release.
McCartney is a different type of album. First, let's talk about that title. This is a name that had been paired with Lennon, separated by a slash, for years-- we weren't used to seeing it all by itself. When the media ran stories on McCartney, he was often just "Paul." He could have called his album Paul McCartney, but he pointedly did not. I think he wanted people to see his name out there as a songwriting credit, without the old prefix. And the album he made has some parallels to Lennon's, too. They share a rawness, a seeming desire to move away from the opulence of 1969's Abbey Road, the last album the Beatles recorded together. But where the rawness of Plastic Ono Band plays into anger, aggression, and disillusionment, the rawness of McCartney is only in the sound. The record has a homespun charm, and a feel that suggests McCartney wasn't putting too much pressure on himself to carry on the Beatles flame or make a statement.
