All the rules fell by the wayside with Revolver, as the Beatles began exploring new sonic territory, lyrical subjects, and styles of composition. The biggest miracle of Revolver may be that the Beatles covered so much new stylistic ground and executed it perfectly on one record, or it may be that all of it holds together perfectly. Either way, its daring sonic adventures and consistently stunning songcraft set the standard for what pop/rock could achieve. Even after Sgt. Pepper's, Revolver stands as the ultimate modern pop album and it's still as emulated as it was upon its original release.
