Isaac Brock (born on July 9, 1975 in Helena, Montana) is an American musician who is best known as the lead singer and guitarist for the indie rock band Modest Mouse, as well as his side project band, Ugly Casanova. When he was a child, Brock and his mother moved around in different religious offshoot circles in the North Mid-West. Around this time, Isaac's mother left his father for his father's brother (Isaac's uncle). His mother's house flooded, forcing her to move in to her new husband's trailer where there was no room for Isaac. So, Isaac stayed behind in the flooded home on the second floor until he was evicted by the police. When he was evicted, Isaac lived in friends' basements until he lived in a shed next to his mother's trailer. It is in this shed that he, Eric Judy (bass) and Jeremiah Green (drums) supposedly first started practicing music together. In March, 1999, a 19-year-old woman filed a police report accusing Brock of rape. Charges were never laid, and Brock maintains his innocence. Brock served a brief stint in jail in Niagara County, New York on an attempted murder charge related to a DUI incident in which his passenger dislocated her thumb. Brock is a former A&R man for the record label Sub Pop; his most notable accomplishment with them was signing Wolf Parade in 2004. In October, 2005, Brock started his own record label called Glacial Pace. The label is a subsidiary of Epic Records (Modest Mouse's record label); its first signing is Minnesotan singer-songwriter Mason Jennings. Brock currently resides in Portland, Oregon.
