Ok first off. How did I not see this and why aren't there 100000000 plays?
I can tell the band is talented, but I can tell they left all the room for the vocals to shine so props on playing nice.
Subsequently, the mix is great and everything sits where it should and stays there. Even leaves headroom for those silky harmonies to really come through too. Which I'm a sucker for.
So Second, I really like the vocal work. Plenty of emotion, and still dynamic. A few points to consider if you think that some of the parts are 'typical tricks' that a vocalist does:
There's some extreme training going on. Standard vocalists do fills and runs in small intervalic distances, and their vibratos are on an on/off switch.
This one uses 7 note scale patterns in wider forms, and even a pentatonic run at 0:52. And a vibrato bloom at 0:58. And an gilbert arpeggio at 3:52. Not another person that just woke up and said "i should sing in a band!"
It's like she plays guitar with her face lol.
Sorry didn't say more about the band- this song isn't really their moment- but I can tell they could do some brutal damage if tempted.
