In 1987, with his friend David Hayes, he cofounded Lookout! Records, which has released records by Operation Ivy, Green Day, Screeching Weasel, The Queers, and scores of other artists. Many of the bands on Lookout! were associated with 924 Gilman Street, a nonprofit, volunteer-run punk-rock club based in Berkeley, California. David Hayes left the label at the end of 1989, and Larry Livermore continued as president and principal owner until he retired in 1997.
In 1992, Livermore and Patrick Hynes formed the Potatomen, a pop band that has released two albums, "Now" and "Iceland," two EPs, "On the Avenue" and "All My Yesterdays," and a split EP, "The Beautiful and Damned/The Day I Said Goodbye," with the Canadian band cub.
From 1987 until 1994, Livermore was a columnist for Maximum Rocknroll magazine, and from 1994 to 2007 wrote a monthly column for Punk Planet magazine. He was also a contributor to the seminal queercore zine Homopunk. In 2008, quarterly periodical Verbicide magazine began publishing his column, titled "Beneath the BQE." Livermore's first column for Verbicide magazine appears in issue 23.
He currently lives in Brooklyn, New York.
