Suggestions for an intro jazz fan

I've always liked Jazz from my old Hollywood obsession in Middle School, but after a drunken trip to New Orleans I have realized my jazz playlist is seriously lacking.

My qualifications for my taste are: -Must have vocals (I like pure instrumentals but for the sake of this playlist, vocals are necessary) -I really love Louis Armstrong and Ella Fitzgerald matchups. Anything along that line is greatly appreciated. -any improv sounding vocal scats are great -idk just anything

THANKS! Help me jump into this wonderful world.
