Jay Bentley

Bentley was a onetime member of such notable L.A. groups as Wasted Youth, T.S.O.L., The Circle Jerks and Cathedral Of Tears. He rejoined Bad Religion in late 1985 while the How Could Hell Be Any Worse? line-up – adding Circle Jerks' Greg Hetson as the band's second guitarist – was reuniting to record the first three reunion albums, Suffer, No Control and Against the Grain, which are often considered their best releases. Today, Bentley continues touring and recording with Bad Religion. He has appeared on every Bad Religion release, with the exceptions of Into the Unknown (1983) and the Back to the Known (1985) EP. The band's most recent studio album, Age of Unreason, was recorded in 2018 and 2019, with a May 1, 2019 release. Since the early 2010s, Bentley has been the regular touring member of Me First And The Gimme Gimmes filling in on bass and backup vocals for Fat Mike.

Bentley has two sons: Miles (born 1991), who played bass in Dave Hause and The Mermaid, and Hunter (born 1993). He also has a daughter named Peribeau and lives with his partner Natalia Fabia in Costa Mesa, California.

In the past, Bentley has had struggles with alcoholism. He first quit drinking in 1990 but relapsed in 1998. Since 2005, he is completely alcohol abstinent.

Jay Bentley grew up in Saugus, California, and later moved to Woodland Hills. As with guitarist Brett Gurewitz and lead singer Greg Graffin, he was a student of El Camino Real High School. He played in Bad Religion for three years (1980–1983), and left while the band was in the midst of writing and recording their second album, Into the Unknown.

Jay Dee Bentley (born June 6, 1964) is the bassist and co-founding member of the punk rock group Bad Religion. He has played with the band through its whole existence with a small break between 1983 and 1985.
