This is the other song I constantly find myself humming from Kate Miss's excellent best-of-2016 playlist. I didn't know the artist, so I googled and found a podcast I wish was in my life years ago. It's called Song Exploder (there's 80+ episodes, most recently Solange and Metallica, so clearly I'm late to the party.).
Each episode consists of an artist breaking down how exactly how a song was created. Which is how I learned the genesis of Get Low's singer-songwriter-meets-minimalism feel and that call and response intro. Not to mention why it has a Lil Jon-esque title.
