First of all, $55 for a 4LP set is a rare and fantastic value in modern new vinyl. I already had the 2015 Geffen pressing of Nevermind and held off on this purchase. What did it for me were the excellent reviews of this pressing, remastering, packaging, and getting Aneurysm (one of their best songs) on vinyl without having to get Incesticide -- an "album" with some interesting inroads, but only for the hardest core.
And nearly 30 years after first listening to this album (as well as Butch Vig's original mix known as the "Devonshire Mix"), I finally get the Beatles comparisons. For starters, you have to understand a bit about Beatles songwriting, which I didn't when I was a teenager. These are essentially pop songs. Kurt was an amazingly talented pop song writer. I read somewhere that his goal when writing a song was to make it as short and memorable/catchy as possible. Then I guess he just covered up his pop tracks by drowning his songs out in sonic chaos. Go back and listen to their first release Bleach (of which there's also a beautiful 20th anniversary edition on vinyl), and you'll hear Nirvana in its raw pop glory.
