There is a song I've found somewhere in the internet awhile ago credited to totally obscure band "Sons of War". It's a live recording presumably from 1986 and the sound is quite good for a Brazilian live recording circa 1986. So does anyone know anything more about this band? And since it's a live recording, probably there should be more tracks???
