Jess Gillam swaps favourite music with singer, rock sitarist and composer Bishi. Together they journey through evocations of space from Meredith Monk, Holst and Roger Webb back home to different shades of the human voice in music - from sacred vocal music from the 15th century, via a Ravi Shankar and Philip Glass collaboration, the unique voice of Beverly Glenn-Copeland and singer Cosmo Sheldrake's wake-up call from the cuckoo.
