Idiosyncratic indie rock duo Quasi paired singer/guitarist/keyboardist Sam Coomes and drummer Janet Weiss, making music that rocked hard and was joyously tuneful when they were so inclined. Hailing from Portland, Oregon, Coomes and Weiss had previously joined forces in the group Motorgoat (and were husband and wife at one point), but with Quasi, they gave themselves permission to let their sense of humor inform both their lyrics and the buoyancy of their music, though they were willing to poke fun at serious subjects (religion on 2001's The Sword of God and post-9/11 American politics on 2003's Hot Shit). While Quasi briefly expanded to a trio with the addition of bassist Joanna Bolme on 2010's American Gong, the core duo of Coomes and Weiss were leading the way when they reunited for 2023's Breaking the Balls of History.

Sam Coomes and Janet Weiss worked for three years with Brad Pedinov in the trio Motorgoat, and when that group split up, Coomes and Weiss opted to continue working together as a duo under the banner Quasi, self-releasing a cassette in 1993 and a split single with Bügsküll the following year. Since both members were working on other projects at the same time (Coomes played in Elliott Smith's band and worked with Built to Spill and Pink Mountain, and Weiss was a member of Sleater-Kinney and performed with Bright Eyes and Stephen Malkmus the Jicks), Quasi would occasionally end up on their back burners, and little was heard from them until 1996, when the duo issued the Early Recordings collection, comprising rare material from 1993 and 1994. In 1997, the same year Weiss joined Sleater-Kinney for their classic Dig Me Out LP, Quasi released their first full-length album RB Transmogrification, issued by the indie label Up Records. Its 1998 follow-up, Featuring Birds, was among the year's most acclaimed independent outings, and in 1999 Quasi resurfaced with Field Studies. By the new millennium, Weiss and Coomes found a new label home with Touch Go. The Sword of God appeared in 2001, marking some of Quasi's sharpest material since their inception and plenty of satiric commentary about organized religion. Two years later, the band's snide sense of humor was highlighted once more on the politics-heavy Hot Shit, which called out the rise of conservatism in the wake of the September 11, 2001 terrorist attacks.

In 2006, the band returned to the studio and, with the help of producer Dave Fridmann, released the rollicking and straightforward When the Going Gets Dark. After adding Jicks bassist Joanna Bolme to the lineup and moving to Kill Rock Stars, the group released its seventh album, American Gong, in February of 2010. Quasi returned to being a duo in 2011 before returning with their eighth album, the sprawling Mole City, in 2013. They unofficially went on hiatus after Mole City, with both Coomes and Weiss devoting their time to other projects, but in 2019, a month after she left Sleater-Kinney, Weiss was involved in a serious auto accident that broke her collarbone and both legs. She was still recuperating at home when the COVID-19 pandemic shut down any options for touring, and with plenty of time on her hands, Weiss and Coomes got together to jam, with their practice sessions helping her regain her skills after time away from the drum kit. They started writing songs together, and in April 2022 they set out on a 27-date tour. Later, they booked time at Robert Lang Studios in Shoreline, Washington, where in five days they recorded Quasi's first album in a decade. Breaking the Balls of History was released on Sub Pop in February 2023. ~ Jason Ankeny & Mark Deming, Rovi
