The globetrotter and trumpeter Gaby Kerdoncuff, gavotte ringer, former member of the groups Gwerz, Skolvan, alongside singer Eric Marchand and taraf de Caransebe, also leads a career rich in influences with his group Kazut de Tyr. But it is perhaps less known, he also contributed to the creation in 1983 of RKB, the Breton radio station in central Brittany and is also a director of musical films. La nuit de la gavotte in Poullaouen pays tribute to him by broadcasting 3 of these documentaries on Friday 16 September.
