Well . . .depends how melodramatic you wish to go. One of my favourite cds is called "Basso Profundo" and gives you that deep booming sound of Slavic hymns.
I believe I have heard of this album from a friend is it possibly a priest-singer who sounds like he has a frog in his throat singing numerous Litanies and with a low level toned Choir (I am not very good at explaining the notations)? I might be wrong but the one I'm suggesting is and the one I like is typical of Bulgarian Chant called Sretenya music and the so-called western Byzantine choir that makes it much more acquired to Western ears. So any Album recommendations would be helpful.
But don't assume I am a big fan of Western Choirs it's Slavic and Sacred Russian thats much preferable than Gregorian and Celtic Women Choirs. And I am still attached back to my Syriac and Indian roots of ecclesiastical music and as well as Byzantine. Right now I am obviously in a Chant Phase right now
. But I do reiterate the point South Indian choirs I've heard have nothing compared to the numerous amount of Slavic I have been listening to over the past year.
