Scott Walker (born Noel Scott Engel; January 9, 1943 – March 22, 2019) was an American-born British singer-songwriter, composer and record producer. Walker was known for his distinctive baritone voice and an unorthodox career path which took him from 1960s teen pop icon to 21st-century avant-garde musician. Walker's success was largely in the United Kingdom, where his first three solo albums reached the top ten. He lived in the UK from 1965 and became a UK citizen in 1970.Rising to fame in the mid-1960s as frontman of the pop music trio the Walker Brothers, he began a solo career with 1967's Scott, moving toward an increasingly challenging style on late-1960s baroque pop albums such as Scott 3 and Scott 4 (both 1969). After sales of his solo work started to decrease, he reunited with the Walker Brothers in the mid-1970s. From the mid-1980s onward, Walker revived his solo career while moving in an increasingly avant-garde direction; of this period in his career, The Guardian said "imagine Andy Williams reinventing himself as Stockhausen". Walker's 1960s recordings experienced a critical revival in the 1980s among the UK's underground music scene, and his subsequent experimental works garnered a cult following. Walker continued to record and release music until 2018, and was last signed to the label 4AD. He was described by the BBC upon his death as "one of the most enigmatic and influential figures in rock history".
