Band name - help!

I'm trying to think of a band's name.

Clues are:

Monster riff from about 2011, 2012 or maybe 2013.

I saw them first on Later With Jools Holland.

Girl singer guitarist, possibly a duo, just drums and guitar but I'm not sure.

American I'm 99pc sure.

Riff is as powerful as Seven Nation Army, but obviously different. Not unlike some Royal Blood riffs.

I used to have the track saved on a Spotify playlist but I lost it when I had to reboot my account last year.

I heard it on telly recently and I just can't think of the band's name. I have tried lots of google searches but out of desperation I am now turning here!

Would you know it if you read it again ?

Cos if so : https://en.wikipedia.org/wiki/List_o..._Jools_Holland

Thanks. Found it in the full series listing.

Series 42, Episode 7.

Deap Vally. "Baby I Call Hell"

Right up Crafty's street I reckon.
