As far as I'm concerned, Lanthanein from Argentina may as well join that list. This duo brings us a stunning blend of nineties doom and gothic metal with the bombast of opera. Furthermore, Marilí Portorrico is a brilliant vocalist who brings a lot of power and emotion to the music. The result is simply epic, perhaps a slower version of Therion but nonetheless with a lot of vigour. On the other hand, there's lot of passages worth a fierce headbanging session.
What I like most about this e.p. is the fact that the band doesn't just play symphonic metal with soprano vocals. The four songs are actually intense pieces of classical music and opera, complete with several kinds of strings and bells, fortified by distorted guitars and pounding drums. Here and there some death growls are present as well, completing the whole concept of this great act.
I can't really say which of the four songs on Nocturnálgica is my favourite (although I have a slight preference for 'Lacrimosa Et Gementem'), mainly because I like the whole thing equally. I love the bombastic nature and the crushing guitars as well as the melodic passages and overwhelming dark atmosphere. All these elements are present in all of the songs, making them perfect for live performances. I'm not sure if Lanthanein ever plays live but if they do, I want to see that...
