Jessica Hernandez and the Deltas

I think your easy comparison is Amy Winehouse, as this is retro-tastic music with a strong voiced female lead.  The Detroit version of Winehouse.  I think this music is a little harder, a little less slavish to the past and a little more current.  But in the same family tree for sure. Her voice is kick ass, and the backing band (5 dudes) is solid throughout the entire debut album, 2014's Secret Evil.

Right after saying that she isn't firmly welded to the past, here is her most popular track on Spotify (265k listens), called "Sorry I Stole Your Man," which is entirely wedged in old school soul and girl group history. 

That stuff right there is cool.  Just let yourself enjoy it for a second, and you'll be grooving around in no time.  Sweet.  In addition to that one, she's got some good song titles, such as "Neck Tattoo," "Dead Brains," and the confusingly difficult to do at the same time instructions from two separate songs, "Cry Cry Cry" and "Run Run Run."  The second most popular track is called "Lovers First," right up there with 239k listens.  But there is no good video of that track, so here is a live version of third place track, "No Place Left to Hide."

It's her voice that sounds like a throw-back, that variable little tremolo in between brassy notes.  A different brand of high-energy soul.  Interesting sound, I've been happy coming back for more of it all day long.
