the Black Keys - except that they're white. I will assume their name is more about the sharp and flat notes of the piano.
Still - they do get the praise. I don't know them enough to say if they are that hugely popular, but I can tell you when they played Cleveland last, they sold out the arena venue.....and in an extremely short amount of time.
I don't know many of their songs either, though I do know this one - as it is maybe six years old.
Their "Lonely Boy" is not a remake of the same named song by Andrew Gold. I'll wait, while you collectively groan.
It's a rock song....a little distortion, a decent chorus / verse thing going on. It's kind of fun.
As for the video - if you watch between 0:00:08 and 0:00:16 - that is how I usually dance, though mostly around the house.
