Query: Beatles Head Toward Psychedelia

Revolver encompasses most, if not all of the beatles wide-ranging strengths: masterful recording, creativity, adept songwriting, psychedelia, and variety in style.Some highlights on this album: "Taxman" (one of Harrison's best rock songs), "Eleanor Rigby" (perhaps McCartney's most powerful and somber song yet), "I'm Only Sleeping" (a cool, sublime Lennon song), "Tomorrow Never Knows" (a Lennon precursor of psychadelic things to come), "Here, There and Everywhere" (a beautifully crafted McCartney ballad). Other notable songs include "Good Day Sunshine," "Yellow Submarine," "For No One," all McCartney compositions.Recorded in 1966, around the time when they stopped touring, this album doesn't lag in any area music-making. It marks a key transition from the Beatles' short, radio-friendly, and carefully-crafted pop songs to more lengthy, uninhibited, and groundbreaking songwriting that would follow.
