 The songs reflect the group's interest in the drug LSD, Eastern philosophy and the avant-garde while addressing themes such as death and transcendence from material concerns.With no plans to reproduce their new material in concert, the band made liberal use of automatic double tracking, varispeed, reversed tapes, close audio miking, and instruments outside of their standard live set-up.Among its innovative tracks are the psychedelic "Tomorrow Never Knows", recorded using tape loops controlled on several machines simultaneously; "Eleanor Rigby", a meditation on loneliness featuring a string octet as its only musical backing; and "Love You To", a foray into Hindustani classical music.
