By day, John Cavanagh is the voice that launched a thousand BBC shows, a Scottish audio chameleon who's whispered sweet nothings across all five radio networks. By night, he transforms into Phosphene, a musical alchemist turning soundwaves into gold. This Jekyll and Hyde of the airwaves has spent two decades proving that the only thing more versatile than his voice is his career choices. When not busy making listeners swoon or mics boom, John's been caught red-handed contributing to "Yesterday's Sunshine Today," a Nirvana (UK) tribute album – because apparently, conquering radio and indie music wasn't enough of a challenge.
