Thought I'd do a different sub-genre of metal today.
Tacere is a Gothic Metal band. They have a male vocalist and a female vocalist (who recently left the band) although the female vocals are dominant. This album is made up of five years worth of demos, and the effort definetly shows. If you're sort of into the Gothic/Symphonic sort of Metal genres then I would recommend giving this a listen to.
