Long time Beatles fan here.
Their trilogy “Rubber Soul, Revolver, Sgt Pepper” is arguably the greatest trilogy of albums ever created.
What’s more, they were released within a very short time period which it even more extraordinary considering todays “artists” can take 3 years or more to do just 1 album of much lesser quality.
1965-December “Rubber Soul”
1966-August “Revolver”
1967-June “Sgt Pepper”
It is extraordinary — almost unbelievable — that those three albums were released in just 18 months.
