Personally, I consider it to be a musical - and production - masterpiece. I'm not even that big of a Beach Boys fan, really... but this album was so amazing - in performances, engineering and production... and I still think it's amazing. Absolute proof that the music should always be the primary foundation of any project, but when married to technology - in this case, the technology of the time - true art is born. This album, much like The Beatle's Sgt. Pepper, is a sonic painting... textures, space, depth, it's got it all. Even the mono version that I heard some years ago sounded fantastic to me. Vocals and harmonies are stellar, and at a time in recording history when the singers and players needed to get it right during the performance... there was no pitch correction in those days, no copy-paste choruses... Personally speaking, I think this album should be required listening for audio engineering students. Anyway, enjoy.
