Michael Bishop (Born 8 September 1968) is an American musician. He attended Thomas Dale High School in Chester, Virginia. Most notably, he was the bass guitarist for the American heavy metal band Gwar. Bishop's first band was the Hopewell, VA-based hardcore outfit The Guilty. As a member of Gwar, he was the first to play the role of "Beefcake the Mighty". The name of Beefcake was taken from Bishop's nickname during his punk years. Bishop was the bassist and lead vocalist for Kepone from 1991 through the band's breakup in 1997. All three members of Kepone later performed together again as American Grizzly until that band's breakup in 2005. He played with the Misery Brothers, a country/soul band local to Charlottesville, Virginia from 2007 to 2009.
Bishop remains an active musician, performing with Sarah White and the Pearls. Since 2011, Kepone has reunited to play occasional shows, although it remains unknown if the band will create any new music. Outside of perfoming, Bishop teaches undergraduate courses in American music history and writing at the University of Virginia.
As of August 2014, Bishop is lead vocalist for GWAR as new character Blothar, replacing late former singer Dave Brockie in GWAR's fall tour.
