Jeremy "Jaz" Coleman (born 26 February 1960, Cheltenham, Gloucestershire, England) is a musician, composer, singer-songwriter and record producer. He came to prominence in the early 1980s as the lead vocalist and occasional keyboardist of post-punk group Killing Joke.
Known for his unique voice and stage presence (occasionally appearing wearing face makeup), Bill Janovitz, writer for the website Allmusic, described Coleman's stage presence and voice as "almost always full-on in his approach, with a terrifying growl of a voice that is similar to that of Motörhead's Lemmy".
Killing Joke's song "The Wait" was covered by Metallica on the $5.98 E.P. in 1987 and was later featured on Garage, Inc., and frontman James Hetfield picked Coleman as one of his favourite singers.
In addition, Coleman has composed orchestral and soundtrack pieces.
