Just found this! Very pleased.
Released in 2013: Black Oath. Nice tempo. Good (not great) vocal harmonies. No banshee screaming or cookie monster. If this is their freshman effort, I expect great things from them in their future. I'll be putting these guys on the short list for my next purchase.
In what is arguably the finest expression of the form, we present Blood of the Sun. For the quality of music that this band puts out, they seem to be dancing with obscurity. We're not aware of any particulars of this band. They just write and perform music that evokes 1971 at its finest.
