Nasty Suicide (born Jan-Markus Stenfors on 27 February 1963) is the ex-rhythm, lead guitarist and one of the founding members of Hanoi Rocks between 1979–1985. Hanoi Rocks was a Finnish rock band that combined elements of punk, glam rock, rock and roll, and blues. Before his tenure in Hanoi Rocks, Suicide played guitar in a Finnish punk band called Briard in the late 1970s. Suicide replaced Andy McCoy in Briard after McCoy joined Pelle Miljoona Oy. After the breakup of Hanoi Rocks in 1985, he and his former band mate Andy McCoy recorded an acoustic album under the name The Suicide Twins which was released in 1986 and was titled Silver Missiles and Nightingales. At the same time McCoy and Suicide started The Cherry Bombz, which included Timo Caltio on bass (later replaced by Dave Tregenna), Terry Chimes on drums and singer Anita Chellemah. The Cherry Bombz released two EPs: The Cherry Bombz (1985) and House Of Ecstasy (1986) as well as a live album, Coming Down Slow (1986). After The Cherry Bombz Nasty went on to form his own band Cheap and Nasty, from 1990 to 1994.
In 1988 Suicide made a short appearance in Guns N' Roses music video for "Paradise City".
Nasty Suicide also appears on Michael Monroe's second solo album Not Fakin' It, released in 1989, as a co-writer and guitarist. Suicide was also a member of Monroe's band Demolition 23 in the early nineties, where he replaced the original guitarist. After the breakup of Demolition 23 Suicide recorded an album under his given name, titled "Vinegar Blood" in 1995 and was released in Finland only.
Suicide retired from the rock scene in mid-nineties and moved back to Finland (which was the reason why Demolition 23 broke up), where he finally finished his studies in High School. After graduating from High School he educated himself as a pharmacist and works currently in a drug company in Finland. Suicide made a few guest appearances with the reformed Hanoi Rocks in the 2000s.
In 2010 Suicide also played a show with Michael Monroe in August 2010 at Ankkarock Festival replacing Steve Conte who had to cancel due to family reasons.
