You don't have to go to Ireland to hear Celtic music any longer. A growing diaspora of groups like Vancouver's Spirit of the West play tradition-minded Folk-Rock with prominent touches of deep green. This is arguably the most widely diversified act of the lot. Witness Open Heart Symphony (1996), a rangy experiment that combines modern conventional Celtic instruments, alternative rock elements and sweeping symphonic flourishes. The album even contains a tribute to Radiohead (the song "Let the Ass Bray"). Blimey!
