It's not as though we can keep burning coal in our power plants. Coal is a finite resource, too. We must find alternatives, and it's a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere.

Imogen Poots loves music to death and can literally name 300 bands that she listens to, that you've never heard. She's so heavy into the underground music scene. When she's speaking on music, she means it.

I was going to be a musician, no matter what it took. I supported myself with blue-collared jobs so I could write music and be in a band and play shows. I even got into an underground art scene. I was going to do whatever.

My sense of politics and justice was deeply shaped in adolescence by my involvement with the underground punk - rock scene, and though lots of social and political issues had come forth in my comics, it wasn't until my late 20s that I felt properly equipped to address certain issues of race, power, and violence in my work.

And I tell you, having girls has made me a much better man. I have friends who are fathers, but they only have boys, and they have the same attitude toward women they always had, you know? And I don't play that... My girls, you mess with them? I will bury you underground.

There's a lot more hypocrisy than before. Racism has gone back underground.

For every prohibition you create, you also create an underground.

Consider a tree for a moment. As beautiful as trees are to look at, we don't see what goes on underground - as they grow roots. Trees must develop deep roots in order to grow strong and produce their beauty. But we don't see the roots. We just see and enjoy the beauty. In much the same way, what goes on inside of us is like the roots of a tree.

The song 'Bite the Thong' in particular, with Damon Albarn, really encapsulates the whole dilemma of, 'Hmm, should I stay on the underground when everybody else is selling out?' Nowadays, you can just do it - have your name-brand clothes, do songs with rock n' rollers - and it's not considered selling out.

To be honest, it was slavery. Nobody should have any romantic ideas about working underground. It's very, very dangerous. You always knew you were living in danger. You were on your hands and knees half the day.

The artist one day falls through a hole in the brambles, and from that moment he is following the dark rapids of an underground river which may sometimes flow so near to the surface that the laughing picnic parties are heard above.

The baby boomers' politics have covered a wide band of silliness, from the Weather Underground to the Timothy McVeigh types. The great majority of us are well in the middle of that spectrum, but still, there's been both leftie silliness and right-wing silliness.

'Zone One' has one kind of an apocalypse, and 'The Underground Railroad' another. In both cases, the narrators are animated by a hope in a better place of refuge - in the last surviving human outpost, Up North. Does it exist? They can only believe.

If Nirvana had remained a small, underground punk rock band, Kurt Cobain would still be alive. And he'd probably be living in Seattle, getting kind of fat and balding, be relatively happy and producing records for other people.

Well, me and Freaky been knowing each other for a while, and he was always playing crazy music in his room, but he would never release it. He's, like, the most underground rapper I know, and he's crazy talented.

Underground, raw movies that come out of nowhere and change everything - they aren't slick-looking. But I have nothing against slick-looking as long as the scripts are funny.

I feel like I just wanna go back to being more underground.

What Public Enemy and Underground Resistance had in common was a rejection of the idea of music as entertainment.

You gotta look beyond the mainstream... the mainstream'll drown you, you know? There's always a pulse in the underground that I love. And the pulse in the underground is what keeps heavy metal alive.

Fear has many eyes and can see things underground.
