It's close, but The Beatles win; without [i]Sgt. Peppers[/i] there probably is no [i]Pet Sounds[/i]. The Beatles were so fast ahead of their time, wstch that vid about "Tomorrow Never Knows" from [i]Revolver[/i]...absolutely groundbreaking. And there really was no "Beach Boys," it was Brian Wilson and The Wrecking Crew.
