The death is confirmed on the band's Facebook page.

"It is with deep sadness that we must announce that our brother, our friend and a true legend in heavy metal music has passed away," Metal Church wrote on Facebook.

Metal Church was formed in San Francisco in 1980, but Mike Howe did not become a member until eight years later.

He left the band in connection with their split in 1996 but became a member again in 2015, after the band was reunited.

During his time at Metal Church, they released a total of five albums, most recently "Damned if you do" 2018.
