The double compilation 1962-1966 / 1967-1970 frames The Beatles' leap from scrappy Merseybeat singles to full-on studio psychedelia and baroque pop. Issued on Apple Records, the set juxtaposes early uptempo rock and pop—jangly guitars and punchy backbeats—with later psychedelic rock and baroque pop’s layered strings, Mellotron and tape-loop experiments. John Lennon and Paul McCartney’s songwriting anchors the collection while George Harrison’s raga touches and Ringo Starr’s steady grooves reveal the band’s broadened palette.
