Now in its third year, BBC Radio 3's World Routes Academy mentoring project turns to Latin America.

Born in London of Colombian descent, 2012's young apprentice is self-taught 20-year-old accordionist, singer and guitarist José Hernando Arias Noguera.

His mentor, the renowned Bogotá-based accordion king Egidio Cuadrado - who brings his own band - is probably best known for his collaborations with Carlos Vives, the Latin American superstar actor-turned-singer.

Fusing the folk tradition of vallenato with elements of rock and pop has proved a game-changer for music now enjoyed all over the Spanish-speaking world and beyond.
