Whoa, Black Betty

What is it with these 'black-something' bands? I just realized how many I listen to. It's like a trend or something. 

The Black Angels

The Black Crowes

Black Flag

The Black Keys

Black Moth Super Rainbow

Black Mountain

Black Rebel Motorcycle Club 

Black Sabbath

Blackfoot

And my friend Matt just turned me on to a really awesome Canadian outfit called Black Pistol Fire (which is what got me thinking about this in the first place).

Meanwhile, for the opposite side, I can only think of The White Stripes and Whitesnake offhand.
