The best of summer in France? Without doubt, the concerts. Jazz in a stunning courtyard by the river. Recently, a trio of musicians came to Gaillac hot from Marciac – a jazz festival in rural France (think fields of sunflowers) begun in 1978 which attracts big names – Diana Krall, Wynton Marsalis, Dizzie Gillespie, Lionel Hampton, Ray Charles, Keith Jarrett have all played there.
