Hanoi Rocks is a Finnish rock band formed in 1979, whose most successful period came in the early 1980s. The band broke up in 1985 due largely to the death of their drummer. The vocalist Michael Monroe and guitarist Andy McCoy from the original line-up came back together in 2002, and have been playing under the Hanoi Rocks name. Hanoi Rocks announced that they will break up again after playing all planned concerts, the last one of them being in March 2009.
