As a kid growing up in the bubble that is the Orkney Islands, discovering punk rock really did change my life. Everything I have done since can be traced back to seeing Green Day perform Welcome to Paradise on Top of the Pops. It was music with real meaning, music that mattered. From there, I got into The Clash. At the moment, I can't get enough of folkpunk singer- songwriter Frank Turner. He literally sings my soul. Having said all that, though, I still quite enjoy 5ive and S Club 7!
The first book that truly blew my mind at a young age was Ishmael by Daniel Quinn. It showed me that whatever assumptions and perceptions we have of society, they are all just social constructs. Anything can change if we really want to make it happen. On a side note, I think every teacher and lecturer in the country should be required to read Walking on Water by Derrick Jensen before they start their job.
I really enjoy films that actually say something or challenge the perceived norms of our culture; American History X, Dances with Wolves and Fight Club spring immediately to mind. I recently saw Into the Wild, which was incredible. Documentary-wise, I would recommend the recent You've Been Trumped, about Donald Trump's golf course near Aberdeen, and anything by John Pilger. His films always test your view of the world.
The only show I never miss is The Apprentice. It probably represents everything that is wrong with society but it's incredibly compelling viewing. I also love political satire and it seems to be making a real comeback; Channel 4's 10 O'Clock Live was phenomenal.
