Bands with appropriate (or inappropriate) names
 

A lot of bands don't, but there are some who when you hear their name you can kind of picture either what they're going to look like or sound like, or what they stand for, and if you didn't know the genre they operate in you could probably guess from their name.

Who do you think fits this bill?

For me, you know what to expect, even if you've never heard the bands, when you hear these names:
Slayer
Motorhead
Black Sabbath
Manowar
Cannibal Corpse
Iron Maiden (yeah they're all working out as metal bands so far aren't they?)
Twisted Sister

What about the reverse?

You hear Styx for the first time, probably thinking of doom or death metal (if you know your Greek mythology) but no, a pomp/AOR band

Can't think of any others at this hour at the moment...

Appropriate
Deströyer 666—These guys sound almost exactly how you think they'd sound: rowdy metal.
Charlie Hunter Trio—Is a jazz trio. Surprise, surprise.

Inappropriate
Massive Attack—They sound like they'd be very in-your-face and aggressive rather than the chilled out, atmospheric band that they are.
Bohren & der Club of Gore—I would expect something avant-garde, violent and provocative, rather than the ultra-minimalistic jazz they play.

Inappropriate

Tony Danza Tap Dancing Extravaganza - It's not a sexy Italian guy tap dancing I'll tell you that much.

And yet it still somehow suits their sound.

Inappropriate: The Pop Group. But that's kind of the point.

Also Swans. But that too is the point.

I think all of these bands are deceiving.

Onyx
Shit Robot
Star Fucker

yEAH, my mate thought they were actual pop, jokes on him

Acid House Kings
Eagles of Death Metal
I'm from Barcelona (they're not from Barcelona, they are from Jönköping, Sweden.)
Brazilian Girls (they are not from Brazil, they are from NYC)
Cheap Girls (they're an all male band)

How is Onyx deceptive?
