If you wanna hear her do some jazz you should watch her Live at the Wynn performance. She has some jazz elements in the beginning including scatting and a lot of vocal improvisations
This is a silly video. I mean I guess it's alright if you want a spam of Bey riffs and runs. But all of these are much more impressive within an entire performance. I recommend All Night Live at Tidal.
Love how you are taking your time and wanting to get to know Beyoncés performances and discography before getting into homecoming. Even if it takes a few months
