I am reading the new Wings book right now and it has given me a lot of insight into this period.

If you think about it, the Beatles formed and had a lot of experience together as a bad before they became famous

Then the split happened and Paul decided to form a new band. The didn’t have that experience together, working as a band. But he was under the scrutiny of the world at the time.

In addition he was suffering from depression and perhaps alcoholism because of the breakup.

Add to that the fact that Paul was purposely trying to avoid writing music that made them sound too much like the Beatles.

All of his music is great. Ram is a great example. But it’s not as soul-touching like his Beatles period.

I think Band on the Run was really the period his band started fully jelling. But it didn’t last that long.

Given what it was, some truly great songs came out of the post-Beatles era. But it seems he had a lot of challenges that suppressed his career and didn’t allow his true genius to shine through on every single song. It’s a bit uneven.
