Scott Walker (born Noel Scott Engel; January 9, 1943) is an American-born British singer-songwriter, composer and record producer. Walker is noted for his distinctive baritone voice and for the unorthodox career path that has taken him from 1960s pop icon to 21st-century avant-garde musician. Walker's success has largely been in the United Kingdom, where his first three solo albums reached the top ten. He has lived in the UK since 1965 and became a British citizen in 1970. First coming to fame in the mid-1960s as frontman of the successful pop music trio The Walker Brothers, Walker began a solo career with 1967's Scott, moving toward an increasingly challenging baroque pop style on late '60s albums such as Scott 3 (1969) and Scott 4 (1969). His solo work drew acclaim but resulted in diminished commercial sales, leading him to reunite with Walker Brothers in the mid-1970s. Since the mid-1980s, Walker has revived his solo career while moving in an increasingly avant-garde direction that The Guardian has likened to "Andy Williams reinventing himself as Stockhausen." Walker continues to release solo material and is currently signed to 4AD Records. As a record producer or guest performer, he has worked with a number of artists including Pulp, Ute Lemper, Sunn O))) and Bat for Lashes.
