Wall Of Berlin is the ninth track on Prince’s 33rd studio album Lotusflow3r.
Basic tracking took place on 19 November 2004, during a three-and-a-half hour session with Michael B. on drums and Sonny T. on bass at Paisley Park Studios in Chanhassen, Minnesota that also yielded 3121, From The Lotus..., ...Back 2 The Lotus, Colonized Mind, Love Like Jazz, Planet Earth, Guitar, Shameless and others tracks. In an August 2006 interview, Michael B. said they recorded eleven or twelve tracks that night. On a different occasion he later indicated that this was the last recording session they did with Prince for a while after that.
The phrase used in the title, "wall of Berlin", was also used in the track 3121, also recorded with Michael B. and Sonny T. during the same set of sessions. The track was premiered on Los Angeles radio station Indie 103 on 18 December 2008, along with Crimson And Clover, Colonized Mind and 4ever. The party noises heard at the end of the track are, in fact, the beginning of the album’s following track, $, for which recording details are listed in its respective song entry.
The "wall of Berlin" is a reference to the Berlin Wall, which divided the cities of West Berlin and East Berlin (and the countries of West Germany and East Germany, respectively) until its fall in 1989.
