Yeah i would say sgt peppers but piper its not bad at all, great music to be their first record, but guys sgt peppers its fine, but better is revolver, the white album, abbey road, those are real beatles albums, not even say Rubber Soul.
But another guy was saying that the beatles in 1964 were singiing I wanna Hold Your HAnd and in 1967 they were in Sgt Peppers. Floyd was doing almost the same, 1967 they were in Bike, astronomi domine and just 2 years they come along with Echos, so these guys were pretty good too.
