He is best known as the frontman for American indie rock band the Airborne Toxic Event as well as the author of the New York Times bestselling memoir Hollywood Park (2020).

During high school, Jollett participated in California YMCA Youth & Government's Model Legislature & Court program and served as the Speaker of the Assembly in 1992.

In keeping with his literary background, Jollett named the band after a section of Don DeLillo's postmodern novel White Noise,[17] which won the National Book Award in 1985.

The band was born of a similar life-altering sequence of events, and thus, the themes of mortality and media consumption that arise from the novel's toxic cloud serve as a major impetus for Jollett's creative drive.

The Airborne Toxic Event's debut album received favorable reviews from such outlets as the Los Angeles Times, Newsweek, Q, and Entertainment Weekly.

They have developed a loyal live fan base with performances at many festivals including Coachella and Lollapalooza while headlining shows at the Greek Theatre, Central Park's Summer Stage and Red Rocks with the Colorado Symphony.
