This disagreement over the influence of VU -v- Sgt. Pepper's is interesting.

Both releases were huge.

But I would argue that 1967 was a HUGE year for many reasons.

I have an album from that year that changed the face of music more than both of those reflected above..................

What about ... ARE YOU EXPERIENCED ? from Hendrix ?

I'd even argue that DISRAELI GEARS is a close alternative as well.
