Good post @lonemountain. I was a huge Beach Boys fan through the All Summer Long album (1964), and they were the first group I saw live (that summer). I had a ticket to see The Beatles on their ’64 tour, but decided to pass. I wasn’t yet sold on them, but did see them the following summer.
The next BB album was The Beach Boys Today in March of ’65, and by the time it came out Pop music had changed dramatically, the harder sound of the British Invasion bands making the BB’s sound passe’, far too gentle and "white". I never even heard the next album Summer Days, and The Beach Boys were effectively dead to me.
No one I knew bought Pet Sounds when it was released in ’66, and I heard it only after accidentally getting a copy of Smiley Smile in early ’68. In the midst of the Blues revival and psychedelic madness of 1968, here comes the strangest music I had ever heard. I became obsessed with SS, and Brian Wilson in general. So I then bought all the albums I had missed after All Summer Long, including of course Pet Sounds.
The album is rather poorly recorded, making it hard to hear all the marvelous voicings in Brian’s piano playing, or to fully appreciate the sublime chord progressions (I consider "God Only Knows" a masterpiece of a song, one of the best written in the 20th century) and orchestration he wrote for The Wrecking Crew musicians to play. You have to work to hear through the "fog" (lack of transparency and inner detail) of the recording, but it’s worth it.
