Hanoi Rocks was a Finnish rock band formed in 1979, whose most successful period came in the early 1980s. The band broke up in 1985 after the death of their drummer, Nicholas "Razzle" Dingley. Original members vocalist Michael Monroe and guitarist Andy McCoy came back together in 2001 and were active with the new line-up of Hanoi Rocks until 2009.
In the 80s Hanoi Rocks was the most successful Finnish band internationally and are still popular in the United States, Japan, and England. They were also one of the first rock bands to tour in Asia, and were the first western rock band to play in Delhi. According to Finnish radio and TV personality Jone Nikula (who was also Hanoi Rocks' tour manager in the 2000s), Hanoi Rocks' albums have sold between 7,800,000 and 10,000,000 copies around the world, but mostly in Scandinavia and Japan. Although their album sales are strong, they are more widely known for their energetic live performances.
