Harry Lime famously declared that after 500 years of peace and brotherly love the only thing Switzerland had produced was the cuckoo clock, how wrong he was!Echoes of Home is a delightfully bonkers documentary all about the Swiss music form of yodelling; a truly unique look at a sometimes misunderstood music tradition and its bright future. From old traditionalists to young experimenters and innovators this is a film for anyone who has seen the Sound of Music and wants to sing with arms wide in celebratory abandon!
