Isaac Brock (born on July 9, 1975) is the lead singer, guitarist, banjoist, and songwriter for the American indie rock band Modest Mouse, as well as his side project band, Ugly Casanova. As a singer he is easily distinguished by his slight lisp, fast pace delivery, vocal pitching and shouting. As a guitarist he shows an aptitude for harmonics, bends, and pick scrapes. Isaac Brock is also notable for screaming into his guitar pickups. As a songwriter he is noted for his clever wordplay and frequent use of metaphors, philosophical lyrics, themes of oppressive rural lifestyles, and certain phrases and sayings commonly used in the early- to mid-20th century and in blue collar environments.
During his childhood, Brock and his mother moved around in different offshoot circles throughout the Pacific Northwest. Brock was home-schooled for part of his school career. When his mother's house flooded she was forced to move in to her new husband's trailer where there was no room for Brock, so he stayed behind. He lived on the second floor of the flooded home until he was evicted by the police. After a period of living in a friend's basement, he moved into a shed he built on the land next to his mother and stepfather's trailer. It was there that he, Eric Judy (bass) and Jeremiah Green (drums) first started practicing music together.
Although many of his songs use religious themes, Brock describes himself as "not really religious at all," adding that "I'm 100 percent on the whole Christianity thing being a crock of shit, pretty much." He claims to "toy around with the whole Biblical thing," because it "just has amazing characters" and also identifies himself as "pretty much" an atheist.
His songs have also addressed his substance abuse, as in "The Good Times Are Killing Me." Brock admits to past drug use, and now says that drugs are "just something I kind of have to fight... I just try and make sure that it's not around, or I'm not around it."
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.
Isaac currently resides in Portland, Oregon.
Isaac's main guitar is custom made by Wicks Guitars. His amps are custom made by Soursound, based on a Fender SuperSix, but are highly modified.
In October 2005, Brock started his own record label called Glacial Pace. The label used to be a subsidiary of Epic Records, but is now independent. Its first signee was Minnesota songwriter Mason Jennings, followed by Love As Laughter, Mimicking Birds and Morning Teleportation.
