I listened to this Spotify playlist on a whim some time ago and keep coming back to it. I’m very impressed how much I enjoy it!
I realy enjoy this one:
The second one uses voice more as an instrument than for singing, somewhat like the refrain in Mmm Mmm Mmm Mmm
Both of these tracks you can basically hear the room they were recorded in with the vocals. Pretty cool.
Moses sumney is basically a benchmark artist for vocals
Elis Regina. Brazilian artist, Beautiful female vocals
Also, Suzanne Vega. Tom`s Dinner Acapella
