There are two artists bearing the name Falconer:
1) Falconer is Stefan Weinerhall's (former guitarist of Mithotyn) Swedish power metal project, with strong folk influences, aimed at being similar to Mithotyn, but (in contrast to typical harsh vocal-ed folk metal/viking metal) with clean vocals.
Created in May 1999, the project initially started unnamed. Their self-titled debut album Falconer was released in March 2001. Since then, they've released seven other albums: Chapters from a Vale Forlorn (2002)
