I would like to introduce this band to you because I got to know one of them online recently and he was a great guy. The special thing about Heartmasterz is that Jose is from Mexico and Zeynep (a girl) from Turkey - they have never met in real life and compose their songs via internet. Their music is not really metal, rather rock ballads but Zeyneps voice is very nice! (Just don't mind the drum computer ) There are some samples on their homepage http://heartmasterz.bravepages.com and you might find something on winMX if you're interested. I could recommend the song "1978".
