Feloche is a French musician, singer-songwriter. He brings a childlike curiosity and energy to many different kinds of music - from electro to French song and unchained rock. But his latest album Silbo pays tribute to the whistling language of the island of La Gomera in the Canary Islands. One very personal song he wrote for his mother ended up, like a migrating bird, travelling back to the island and helping revive the language. He tells the tale of how music can be a genuine force for change.
