Foo - Sort of underground music you like

Can you guys tell me some underground or sort of underground music you like? What I mean is in any given group of people they typically have not heard the music? I'm not one of those people who likes a band just for that reason I just need something new that I probably haven't heard before.

Sorry, if I told you, they could get popular, sell out and lose all underground cred.

Yeah I used to hate Indie kids because that summed most of them up. I am the type of person listening to Hoku or Britney Spears one song then moving on to Fugazi, Motorhead, The Pixies, Von Bondie etc in the next song on my ipod. As long as it sounds good I really don't care what other people think I will even bust out some Enya or some hardcore rap like Ghetto Boys

Punk rock man:

Chixdiggit!
Teenage Bottlerocket
7 Seconds
..and other bands I'm too tired to think of right now.

...What I mean is in any given group of people they typically have not heard the music?

Well this probably isn't what you were thinking, but if the main criteria is that you've never heard it before, then I suggest listening to the most gorgeous music on the planet, which is pretty much anything by Marisa Monte, especially when in collaboration with Carlinhos Brown.

Magamalabares (http://www.youtube.com/watch?v=c1-qHjRp-_o) - Marisa Monte and Carlinhos Brown

Maria de Verdade (http://www.youtube.com/watch?v=lwaKe3mBqpY) - Marisa Monte (written by Carlinhos Brown)

Bem Que Se Quis (http://www.youtube.com/watch?v=q3MpsJFOgYI) - Marisa Monte

For underground music there is only the Great stalacpipe organ or lithophone in the Luray Caverns of Virginia. Not only is it the largest musical instrument in the world it has unique tonal qualities. Records of the music were available at The Museum of Jurassic Technology in the LA area. Yes "Virginia" I knew what you really ment. Be careful with the term Underground when near a Mining Engineer.

Lacuna Coil
Theatre of Tragedy

Hmm, underground bands off the top of my head:

Legendary Pink Dots
The Damned
Machine in the Garden
The Sword
Vows in Ashes
Lust Murder Box

Mo' punk rock man.

Black Flag
Descendants
Velvet Underground (they DEFINED punk)
Groovie Ghoulies
Lagwagon (superior drumming, at least for punk music)
Minor Threat (Them and Bad Brains originated fast punk rock)

Post-hardcore/screamo underground rocks.

death metal & grind...

death metal & grind...

Gotta love the pig-squeals.

I'm really into Boston, Kansas, Peter Frampton and REO Speedwagon.

A couple I listen to that aren't widely played on radio as far as I can tell... Don't know that I'd call them underground though. ;)

Junior Brown
Bond

Or a spelunker for that matter ;)
