Surprised there's a few folks that listen to music from this region here on ASR, pretty cool. Problem I have with some female Balkan singers (modern folk especially, but also can be heard in some pop as well), is many of them sound far too nasal-y to where undertones of heavy exhales for some reason are always hovering their vocals. Males suffer something similar, an almost ever-present moaning enunciation of sorts. Now I can't really tell if this is due to the way the music is mastered or what tbh.
Found a recent singer by chance called Džejla Ramović. Relatively new singer but doesn't suffer the common issue I experience with many female singers of the region. She doesn't have too much music of her own as she's still young, but there's a few singles I think ADU would enjoy since he seems like like pop-folk, and there's also Youtube footage of competitions she's participated in, some pretty insane showings really when you consider her years.
Incredible voice, perfectly clear.
You also have great singers like this in general with a re-imagining of a song from an older rock bad of a few decades ago. Top tier love text made into this soulful interpretation
One thing I have to echo about the Balkans (at least the former Yugosalv region) is it has this quite old sort of folk called Sevdalinka (poetic compositions anywhere from a century or half millennia thought to have been purely sung without instruments). Utterly insane quality compositions vetted by time given that the only ones still knowing to us, are the ones that people kept alive throughout the centuries either by whole regions knowing the songs verbally, or my composers who thought to record them (I don't know the specifics but I know you can't by definition compose a "modern Sevdalinka" textually, it literally is some old folk song that was common among a region usually known by the populace but since this was during times that pre-date electronics, it's quite difficult to understand which piece is even theoretically a Sevdalinka these days when verified finds are made). The themes themselves seem to be somewhat lightly comedic, many times emotionally heavy and unbearable unrequited love (like forbidden love between a Christian and Muslim of the era since this was the time the Ottoman Empire was in the region), and sometimes the melancholic underpinnings present during seemingly happy moments.
It seems this sort of pedigree follows Balkan ballads and folk songs into the present day with really great text/story compositions in the music from the recent exposure I've had to some of them. Classic rock/folk rock of the 70's also seemingly benefit from this trend by having really great texts (the same sort of music one might say boomers enjoy like REALLY classic rock not simply for it's instrumentals, but how the music seems to tell a heart gripping tale at times). Sevdalinka as a genre though is (as is the barrier of entry to newly inducted pieces) incredibly high for basically all singers it seems. As far as singing prowess is concerned, everyone in the region agrees if you can sing that genre, that's about as close to objectively claiming "you can truly sing" as one can get (possibly similar to Soprano and things like high tier Soul/Blues level of talent required). It's deceptive because if you look at some of the text, it can seem barely anything at face value. And trying to add emotional heft with ones voice alone I imagine is challenging if trying to deliver it in an instrumentally minimal style. I've only heard of a single vocalist from America even attempt it.
