Warning was a British doom metal band from Harlow, Essex. Founded in 1994 by vocalist, guitarist and songwriter Patrick Walker, the band released two albums and is regarded as highly influential on the doom metal sound.
Following the band's breakup in 2009, Walker continued to release music with a new band 40 Watt Sun, which is now a solo project.
Warning briefly reunited in 2017 to perform Watching from a Distance in its entirety at the Roadburn Festival, which was followed by a tour of the United States and Europe.
