Thanks for the suggestion, but I'm looking for a heavier sound, and much deeper vocals. I'm also a listener of symphonic metal, and mezzo sopranos are everywhere - so for a classically trained female vocalist, I'd be looking for someone squarely in the Contralto range.
As for a Halestorm, I'm just not a fan. An example of a deep female vocalist in metal would Mandragora Scream:
Monotone clean vocals are insanely uncommon in Symphonic Metal. however I can only think of a few in that regard with insanely deep clean vocals. just not in the genre of Symphonic Metal. more in the Gothic Metal / Gothic Rock Genre. simply because a lot of bands in this genre were influenced by Sisters of Mercy and they were arguably one of the earliest bands to sing with that deep monotone voice. also a lot of clean symphonic vocals. the majority of them are female.
@MograineLefay - Insomnium crossed my mind, but I'm not terribly familiar with them. The song you posted almost has the opposite of what I'm looking - deep growls, but higher pitched clean sections. I actually saw Insomnium touring with Dark Tranquility. Speaking of which, they're probably a better example of what I'm looking for:
Interesting, but not what I'm looking for.
That's always rubbed me the wrong way.I honestly can't think of any symphonic metal bands that feature a prominent clean male vocalist. Maybe Nightwish? I think it would be awesome there was a symphonic metal band that feature prominent clean male voclas. Anyway, I'm not quite looking for monotone per say, but more like baritone. :P Gothic metal is amongst my favorite genres, so I do love the suggestions. Thanks for the input!
Tyr is probably the closest to what I'm looking for, but even so, I think the pitch is still a tad high. Korkiklaani is way more raspy than deep.
