Music and Mayhem charts the immersive and explosive life of one of Ireland's most important musicians, and the golden decade of Irish music he was at the very centre of.    Keith Donald's story begins in Unionist east Belfast, hurtling through vivid memories of a childhood as a musical prodigy, first performing at the BBC aged ten. His story takes him to the classics department of Trinity College Dublin in the early 60s, a hotbed of new ideas, before he becomes enveloped in the beauty of tenor sax. Jazz clubs by night and studying classics by day, Donald soon felt the early onset alcohol addiction, fueld by childhood PTSD. From university he joined the booming showband scene with The Federals in Belfast and The Greenbeats in Dublin, touring the dancehalls and marquees of the Irish country.    The 70s saw Donald building a music career in Dublin and Europe, coping with addiction, a crumbling marriage, and forging a separate life as a qualified social worker. It was the 1980s however, when his greatest breakthrough came to pass withthe formation of the Celtic rock supergroup Moving Hearts. With the Hearts Donald was manager, star performer and inspiration, alongside bandmates including Christy Moore and Donal Lunny. Their fusion of jazz, rock and traditional music created the soundtrack of an era and paved the way for a generation of Irish musicians.
