Actually I HAVE been meaning to get at least one Mago de Oz album (whose name means Wizard of Oz) but haven't gotten around to it. The only song I'm really familiar with is Molinos de Viento (Windmills) of which I've seen the video and heard on the radio. Their sound is sort of folk-metal very melodic and not that heavy. They use violins, flutes and other acoustic instruments in their songs.
