Because it’s consistently recognised as one of the most - if the not the most - important pop music records ever, it’s easy to dismiss the telltale signs of madness in Pet Sounds.

The name itself is a little off-kilter, and even weirder when you know it was Brian Wilson’s attempt to pay homage to Phil Spector by using his initials - thanks Brian…

Then there’s the cover image. The Beach Boys - American heart-throbs and cultural icons - awkwardly feeding assorted goats in what looks more like a snap from the family album than the cover to Brian Wilson’s greatest work. Sometimes though, as the music proves, genius and insanity occupy the same space. Pet Sounds is easily the most memorable Beach Boys album cover.
