It's newly minted old school.
Fresh sounding with throwback styling.
Infectious instant classics.
It's a sound that's been popping up for a while now (see; Lilly Allen, Amy Winehouse, Gnarls Barkley/Cee-Lo Green and more), but here's a few artists you may not know.
Fitz and The Tantrums
Sharon Jones and The Dap-Kings
I'm putting The Black Keys on this list too... Harder rockin' but there's SOUL POWER in there!
You may know Aloe Blacc from the first song below, it opens the HBO series "How to make it in America". The second one is just, so, so cool, baby.
