Hey Ted for what rock bands were doing no one was using backwards guitar solos and using thick sitar soundscapes in fact jazz musicians or rock musicians were not doing anything like "Love You To" or "Tomorrow Never Knows".

I think your love of the Beach Boys is blinding your opinion of what the Beatles were doing musically. The Beach Boys were still sounding like Phil Spector while the Beatles were pushing the boundaries of pop music. "A Day in the Life" and "Tomorrow Never Knows" makes Pet Sounds sound dated.
