You have a few choices as to how you would like your Pure McCartney. If you stick with the 2-CD version, you’ll get 39 tracks, mostly the biggest post-Beatles solo hits, with a handful of Wings and Fireman tunes tossed in. Or you can spring for the four-disc, 67-song package, which naturally digs a little deeper into the catalog, unearthing a handful of unjustly ignored gems and more than a few that never got much traction the first time around, some for good reason. Each version starts where the Beatles left off, in 1970 with “Maybe I’m Amazed,” from MCCARTNEY, the solo debut, and goes as far as 2014’s “Hope for the Future,” written and recorded for a video game. One smart move by the compilers was to mix the sets non-chronologically: Songs from the ‘70s sometimes follow songs from the ‘80s and so on, random-shuffle style, the very last track on all versions being “Junk” from that same ‘70 debut. That ping-ponging playing order tends to spread the wealth more evenly so that all the best stuff isn’t concentrated near the top. No matter how you play it though, Pure McCartney is a reminder—not that one is really needed—that this man’s solo discography, while it could never approach that of The Beatles, is remarkably well packed with ingenious songwriting and performance.
