Barrule was a Celtic and folk trio from the Isle of Man consisting of Tom Callister, Jamie Smith, and Adam Rhodes. The group was formed in 2012 and was active until 2017. Barrule's music was a blend of original and traditional Manx language songs. In 2014, they won Best Debut in the Spiral Earth awards, and they went on to perform at major festivals such as WOMAD Charlton Park and the Festival Interceltique de Lorient, where they won the Trophée Loic Raison. The band's name was inspired by the Manx summit and Celtic God Manannán mac Lir.
