The Beatles-White Album (1968)

A year after "Sgt. Pepper's Lonely Hearts Club Band" The Beatles offered a wide repertoire of songs quite different from each other that constituted the double "White Album".
It is also undoubtedly the most rocker album of The Beatles as demonstrated by "Revolution 1", "Helter Skelter" or "Back in The U.S.S.R.".
Along with the aforementioned "Sgt. Pepper's ..." this would become one of the cornerstones of the group, their later global influences are well endorsed in styles such as hard rock, classic rock, pop rock or indie rock.
