South Africa is the only place in the Southern hemisphere where Halloween is really catching on. They have a lot of sporting events that have made it more popular there. They have motocross and rave celebrations, and they're embracing it as a youth culture thing.

I would say there's always a movement of music and fashion in youth culture - every decade inspires the new one.

Since the 1960s, mainstream media has searched out and co-opted the most authentic things it could find in youth culture, whether that was psychedelic culture, anti-war culture, blue jeans culture. Eventually heavy metal culture, rap culture, electronica - they'll look for it and then market it back to kids at the mall.

Club culture is always going to be a reflection of youth culture, but I think we're maybe moving into a time when the club is a place where older people can go, too. And it's a place people go to connect to themselves, it's not always about the party. It's also about letting off steam and expressing yourself and connecting to other people.

All of youth culture is packaged and sold back to us at this furious rate these days. I think it's part and parcel to this corporate encroachment on our lives in general.

In Japan, Australia, and England there is such a strong youth culture.

From 1962 to 1965, the guitar became this icon of youth culture, thanks mostly to the Beatles.

Dress codes and gestures and attitudes have always inspired me, as has youth culture in general, although now I question it more. If you analyze youth cultures over history, there has always been something strict about them - you have to be like this or like that.

The 1970s, the decade of my teenage years, was a transitional period in American youth culture.

Surrounded by a sweltering state known for its staunch conservatism, Austin is an oasis. It's home to the University of Texas, which continuously fosters a well-educated youth culture who have been funneling their collective creative energy into building a vibrant music, film, and technology scene for decades.

Bands like Little Mix do represent youth culture because loads of 16 year old girls listen to them.

I'm interested in youth culture - when your parents are running your life, but you think you're the big man - but I'm not trying to make a statement.

As a teenager, I was always this strange mixture of kind of vice-captain of the rugby team and sensitive artist type the rest of the time. I was sent away to this public school in the middle of nowhere, and I think we managed to completely miss out on normal youth culture.

To her audience, Janis Joplin has remained a symbol, artifact and reminder of late Sixties youth culture. Her popularity never derived from her musical ability, but from her capacity to link her fantasies of freedom and immortality with ours.

With actors, all our ages are out there for all to see - you can't hide anything, really. And it's kind of a relief. This is my age, this is what I look like without makeup on - who cares? That youth culture - that lying about your age - it's all denial of death anyway.

If your audience is young, it'd be youth culture, if your audience is older, it'd be older people, if it were senior citizens, it'd be senior citizen issues. So you try and hit the target audience.

The things that I draw on, and the world that I feel part of, aren't particularly youth culture.

Apathy in youth culture is pretty stark.

Listen, you know this: If there's not a rebellious youth culture, there's no culture at all. It's absolutely essential. It is the future. This is what we're supposed to do as a species, is advance ideas.

Fashion and music are two great artistic forms that can be molded by the youth culture - our taste and our passion for evolving things in our limited time on earth allows us to look at things with fresh eyes.
