is an Argentine-born guitarist. With much of his career as a sideman and guitarist for singer Sting, he has also released several solo albums.
Miller was born in Hurlingham, Argentina to an Irish-born mother and an American-born father who worked for Johnson Wax. When he was ten, his family moved to Racine, Wisconsin, where the Johnson headquarters was located, and moved to London two years later. Returning to Racine, at fifteen, he performed publicly for the first time at a club in Racine as the only white person in a soul music band. He moved to London and studied at Guildhall School of Music, then returned to the U.S. and took a summer course at the Berklee College of Music in Boston. He also took lessons from Brazilian guitarist Sebastião Tapajós.
In the 1980s, Miller toured as a guitarist for World Party and King Swamp. As a session musician he recorded with the Pretenders, Phil Collins, Paul Young, and Level 42. Since 1991, he has recorded and toured with Sting. He co-wrote the hit song "Shape of My Heart" with Sting. He released his debut solo album, First Touch, in 1995, followed by Second Nature and Third World.
In 2003 he released the classical album Shapes, with interpretations of Bach, Beethoven, Edward Elgar, and Tomaso Albinoni.
His son Rufus (b. June 1985 in Hammersmith), also a guitarist, has recently joined the band.
