Known for his work in the folk, rock, blues, soul, Americana, and country music genres, this Northern Irish-born singer and songwriter is notable for such solo albums as The Sailor's Revenge, Let's Start Again, and Domestic Blues, as well as for his collaborations with Steve Earle.
In his teens and early twenties, he performed with the punk group Sellout and the power pop band 10 Past 7. Then, in the late 1980s, he founded a band called Energy Orchard and served as its frontman, rhythm guitarist, and primary songwriter.
His solo album Howl On (2009) was inspired by NASA's Apollo program.
Born Martin Christopher Kennedy, he grew up in Belfast, Northern Ireland, during the politically turbulent period known as The Troubles. He was the son of Jim and Lily Kennedy, the older brother of fellow singer and songwriter Brian Kennedy, the husband of Brenda Boyd and the stepfather of Kenneth Hall and Christine Elliott.
His 2005 album The Big Picture features additional vocals by The Pogues frontman Shane MacGowan.
