Lennon开始个人音乐发展其实是始于1968年的“Unfinished Music, No. 1: Two Virgins”。这是一张他与大野洋子合作的实验噪音专辑。可这张唱片最引人注目的却是封面上列侬与洋子赤裸身体的照片。他们于69年3月20日在直布罗陀结婚。10月出版了“Unfinished Music, No. 2: Life with the Lions”封面上则是洋子怀孕期间两人在医院相对的照片——列侬在这段时间一直陪伴在洋子身旁，直到她后来的流产。随后就是“ The Wedding Album”包括那首“Give Peace A Chance”。在这个时期列侬、洋子与吉他手.Eric Clapton、贝司手 Klaus Voormann 、鼓手 Alan White组成了the Plastic Ono Band。出版了有关列侬与毒瘾的斗争的“Cold Turkey”，但销量却不尽人意。为此列侬退回了女王颁发的帝国勋章，同时抗议英国政府对越战的漠视态度。 by William Ruhlmann John Lennon and Yoko Ono's second collaborative album consists of five tracks: all of side one is taken up by "Cambridge 1969," a live recording at Lady Mitchell Hall in Cambridge of Lennon playing an electric guitar backup to Ono's singing and screaming. Side two includes an a cappella rendering by Ono of "No Bed for Beatle John," which discusses the refusal of a hospital to give Lennon a bed so he could stay during his wife's troubled pregnancy; "Baby's Heartbeat," which is what it says it is; "Two Minutes Silence" in commemoration of Ono's miscarriage, which also is what it says it is; and "Radio Play," 12 minutes of a radio dial being turned back and forth to pick up random stations. If, as they suggested, their lives were their art, then this is, too. Maybe. [The 1997 CD reissue adds two bonus tracks: a previously unreleased version of Ono's "Song for John," and the previously unreleased "Mulberry," which is nine minutes of Yoko's vocal improv backed by careening, atonal guitar runs.]
