I bought Pet Sounds when it was first released having been a Beach Boys fan since their 'surfin' days. It was in mono though - don't know why, even a later cd release was also mono. I always thought the album was perfect for stereo given Brian Wilson's production values and finally a stereo version was issued on vinyl a few years ago, and it didn't disappoint. I think the track Pet Sounds on side 2 is one of the finest stereo productions I've ever heard.
