So how did "Hidden Tracks" come about? Rosalind Stoddart, artistic director of Fermynwoods Contemporary Art, who commissioned the audio tour, explains:

"It all started in my kitchen about two years ago over a cup of coffee with Steve Gibbs of Watch This Space. We were talking about my plans to have two shows by Peter Randall-Page at the same time, one of new sculptures at Lyveden New Bield and the other of his works on paper at Fermynwoods.

"Since the two places are only three miles apart across the fields, I wanted to find some way of linking them more closely - and give people the chance to enjoy the beautiful countryside we have here in a new way.

"So we came up with the idea of creating a tour of the local landscape and its history through sound."
