Sons of Maxwell is a Canadian music duo who perform both traditional Celtic folk music and original compositions with a pop-folk sound. The duo consists of brothers Don Carroll and Dave Carroll, originally from Timmins, Ontario, residing in Halifax, Nova Scotia since 1994. They began singing together while studying at Carleton University in Ottawa under the band name "The Don and Dave Show" in 1989. One recording was released under that name. They re-christened themselves S.O.M in 1993, in honour of their father (Max Carroll). In July 2009 the band became an international media sensation when they released the protest song and music video, "United Breaks Guitars," explaining how after United Airlines personnel damaged their musical instruments, the airline refused to take responsibility or give compensation for the loss. As a result, in addition to his musical career, Dave Carroll regularly gives speeches about customer service.
