Crowbar is an American sludge metalband formed in New Orleans, Louisiana, in 1990. The band is fronted by vocalist/guitarist Kirk Windstein, Crowbar’s sole constant member. Through infusing a slow, low-keyed, brooding doom metal sound with the aggression of hardcore punk, they pioneered a style known as sludge metal – albeit Windstein admitted a mild dislike to the term. The band has released 12 albums and done countless tours around the world over the last 33 years. Currently writing album number 13 which will be released in 2025 by MNRK Heavy. Alongside Windstein, Tommy Buckley ( drums) Matt Brunson( guitar) and Shane Wesley (bass) are Crowbar.
