Personally, I like A LOT the spanish Heavy Metal, it has that "something" that other bands doesn't, maybe it's because of the Lyrics plus the way they sang them!!, the energy and the spanish pronunciation make'em unique!!
I'd like to recommend Subterraneo "Toledo", Thor "Mata a la Bestia", Bruque, Sparto; and of course, the DESCARGA NORTE compilation, with Rock D.A.M. (The two tracks on this comp/split are totally different from the ones in their albums), BO2, Estigia (from their more speed metal period, songs from the demos), UTM and CAID DECEIT!!!! (their two tracks and the demo are just AMAZING!!!!)
Also, do anyone knows the first single of SABLE??, is it as good as SIMBOLOS DE REBELIÓN?
I'm also searching for the HALLEY (Esp) Self Titled LP, do anyone have heard it??, I've just listened one song (Danzad Malditos Danzad) and it's AMAZING!!
P.S.: I think someone should make a topic about Latin American (plus Brazil) Heavy Metal, here in Chile there wasn't too HEAVY metal bands, it was more of an extreme scene, but the rest of Southamerica had some awesome bands...
