ストロベリー・フィールズ・フォーエバー
In February 1967, the Beatles released the double A-side single "Strawberry Fields Forever" / "Penny Lane", which Ian MacDonald says launched both the "English pop-pastoral mood" typified by bands such as Pink Floyd, Family, Traffic and Fairport Convention, and English psychedelia's LSD-inspired preoccupation with "nostalgia for the innocent vision of a child". The Mellotron parts on "Strawberry Fields Forever" remain the most celebrated example of the instrument on a pop or rock recording. According to Simonelli, the two songs heralded the Beatles' brand of Romanticism as a central tenet of psychedelic rock.
