Read about it here:
I mean, seriously, do I even have to say anything here? This album changed the way albums were made forever. Not my favorite album by the BEST BAND EVER, but an incredibly important time in music for them (they quit touring and poured themselves into experimental production techniques). Like 9/11 (or when JFK was murdered or when man walked on the moon, etc.), people remember where they were the first time they heard this album. I would argue that every important album recorded after “Sgt. Pepper’s” used some if not all of the production techniques pioneered here.
