Janaza is interesting. I am sure that being a sole female member of a black metal band in a largely Muslim nation is probably quite controversial. Then there is the fact that Janaza's lyrics for the most part are utterly against Islam as a religion. Janaza plays extremely raw black metal and is part of the Arabic Anti-Islamic Legion, a newer collective of black metal groups speaking out against Islam.
NOTE: I am aware of Acrassicauda, but to this date have not checked them out yet.
