Extreme Cello is an extreme sport and a performance art in which people take a cello to an unusual, often outdoor, location and perform music. It is synonymous with the cello trio known as the Extreme Cellists, an amateur group inspired by the sport of Extreme Ironing. Their performances are generally given to raise money for various charities. Since 2006 the Extreme Cellists have had a particular association with the spinal injuries charity Aspire. According to their official website, Extreme Cello aims to "take musical performances to new heights, and depths, by giving performances in many extreme locations."
