U2 [SEP] "War" (1982–1983)
After the October Tour, U2 decamped to a rented cottage in Howth, where they lived, wrote new songs, and rehearsed for their third album, "War". Significant musical breakthroughs were achieved by the Edge in August 1982 during a two-week period of independent songwriting, while the other band members vacationed and Bono honeymooned with his wife Ali. From September to November, the group recorded "War" at Windmill Lane Studios. Lillywhite, who had a policy of not working with an artist more than twice, was convinced by the group to return as their producer for a third time. The recording sessions featured contributions from violinist Steve Wickham and the female singers of Kid Creole and the Coconuts.
