Unusual musical instruments, including cacti, will be part of a show at the Proms at the Royal Albert Hall.

Music made from the thorns of the desert plant will feature in a special show celebrating the 100th anniversary of the birth of American composer John Cage.

Curator of Cage Music Walk, Tim Hopkins, Conductor Ilan Volkov and Cactus player Robyn Schulkowsky speak about the unique show.
