Mick Barr is described in Wikipedia as "an American avant-garde metal guitarist", which is probably as close as anyone will come to paraphrasing the genre-defying compositions made by Barr and his occasional collaborators. The content of Annwn (comprised entirely of pieces for multiple electric guitars) is his crowning achievement. This album has as much to do with modern classical composition as it does with anything associated with the term "heavy metal". Annwn is an album that'll appeal to anyone with a sense of musical adventure.
