Kirsty Wark presents highlights and performances from the world's biggest festival of arts and culture.

Kirsty interviews hugely influential Man Booker Prize winner James Kelman about his latest novel, Dirt Road - an exploration of grief, race and the power of music, set in America's Deep South.

Love is all around on this year's Fringe and Kirsty talks to playwrights and performers who are exploring the science of attraction, monogamy and our need to reproduce, through science, live experiments and audience interaction.

And as Mogwai, Sigur Ros and Barry Humphries sit side by side with Mahler, Schubert and Bach on the programme for the Edinburgh International Festival, we speak to some of the artists who are helping move the festival in a new direction.
