 You're with the Arts Hour and I'm Nikki Bady. As you'll know if you've been listening to the Arts Hour for a while, I'm a big fan of Serbian performance artist Marina Abramovic. She's been pushing boundaries and expectations for more than four decades with work that often focuses on the body, often her own body, and the possibilities of the mind. Glastonbury Music Festival has been running for 54 years and is one of the biggest in the world with nearly a quarter of a million attendees.
