Pär Anders Fridén (born 25 March 1973) is a Swedish vocalist, best known as the lead singer of the melodic death metal band In Flames.
Coincidentally Mikael Stanne had left In Flames (being only a session player) and switched from rhythm guitar to lead vocals in Dark Tranquillity, so the two effectively traded places.
In 2007 Fridén appeared as a guest vocalist on the Japanese bonus track "See the Falling Sky" on Caliban's 2007 album "The Awakening".
In addition to being a vocalist, Fridén is also a producer, with his most recent efforts being the albums: The Undying Darkness by Caliban in 2006 and Absolute Design by the band Engel in 2007.
He also co-wrote and performed scream vocals on the song "Self vs Self", which appears on the third album of UK/Australian drum and bass band Pendulum alongside his bandmates Björn Gelotte and Peter Iwers.
