Isaac Brock is the lead singer, banjoist, guitarist, and songwriter of the American indie rock band called Modest Mouse. He currently has an estimated net worth of $6 million. He was able to gain this by being the Modest Mouse’s lead singer. He also sings for the band Ugly Cassanova. As a songwriter, he became famous for his clever play of words. He frequently uses philosophical lyrics, metaphors, certain sayings, and phrases as well as oppressive rural lifestyles that people in the early to mid-20th century commonly use in blue-collar environments.
Isaac got inspired by his home state’s rock scene that spawned the Screaming Trees and Nirvana. He formed the Modest Mouse in 1993 and he was originally in the vocals and guitar. His band started to rehearse in a shed near the mobile home of his mother. Since then, they were able to release several albums that include the self-titled Modest mouse in 1994.
