Matti Antero Kristian Fagerholm, better known by his stage name Michael Monroe, is a Finnish rock musician who rose to fame as the vocalist and saxophonist for the glam punk band Hanoi Rocks, and has served as the frontman for all-star side projects, such as Demolition 23 and Jerusalem Slim.

Hanoi Rocks were a Finnish rock band formed in 1979. They were the first Finnish band to chart in the UK and they were also popular in Japan. By 1984, the band was considered to be on the verge of an international breakthrough when they released their first major label album for CBS and headed for their first US tour. The tour was however cut short when their drummer Nicholas "Razzle" Dingley died in a drunk driving incident with Vince Neil behind the wheel in December 1984. The band never recovered from the loss and announced their split in June 1985. After their initial break-up, lead singer Michael Monroe became the first Finnish artist to chart on the American Billboard 200 in 1989. Monroe and original lead guitarist Andy McCoy reunited in 2001 with a new lineup that lasted until 2009. Although musically closer to traditional rock n' roll and punk, Hanoi Rocks has been cited as a major influence in the glam metal genre for bands such as Guns N' Roses, Skid Row and Poison.
