GZR is a band led by
Black Sabbath bassist/lyricist
Geezer Butler. The band has actually been marketed with three different names on the three releases they've had. In 1995, the band was marketed as
g//z/r. In 1997, it was merely
geezer, and in 2005, it was
GZR. Most fans refer to the band as
Geezer, although Butler himself refers to the band name as "gee-zed-R." This incarnation of the band is not to be confused with Geezer's previous attempt in 1985 to form a solo band, then known as
The Geezer Butler Band - the two bands are totally separate.
