I mentioned recently that Pico Iyer, whose latest book is Autumn Light, and Johnny Pitts, author of Afropean, would be speaking in London under the 5×15 banner; you can now listen to their contributions on Soundcloud — see below. There’s a 5×15 session coming up on August 4, at the Wilderness Festival in Cornbury Park, Oxfordshire,  on “our place in the natural world”; speakers will include the writer and broadcaster Nicholas Crane and Isabella Tree, whose latest book, Wilding: the Return of Nature to a British Farm, has been short-listed for the Wainwright Prize (for nature/travel writing focused on Britain).
