Stokes and Pearce originally met in high school, and met both Sinclair and Luketina-Johnston when all four attended classes at the University of Auckland, studying jazz. Prior to The Beths, Luketina-Johnston was performing swing under the moniker of Sal Valentine. Stokes, Pearce and Sinclair were all a part of his backing band, The Babyshakes, for various tenures. The Beths were formed in early 2015, and released their first single "Idea/Intent" via SoundCloud in July of that year. In March 2016, the band independently released their debut EP, Warm Blood. The EP spawned a single, "Whatever," which was released with an accompanying music video in May 2016. A new single, "Great No One," was released in October 2017. The song was the first to be lifted from the band's debut album, Future Me Hates Me. Prior to the album's release in 2018, the bands announced their signing to Carpark Records in the US and to Dew Process in Australia. The album was released globally on 10 August 2018, followed by an international tour supporting the release. The title track was nominated as one of five finalists for the 2018 Silver Scroll award in New Zealand. In 2018, Luketina-Johnston permanently departed from the band to focus on Sal Valentine. In November 2018, the band announced the forthcoming release of a new seven-inch, Have Yourself a Merry Little Christmas. The vinyl features the band's cover of the traditional title track, as well as a demo version of their song "Happy Unhappy." "Happy Unhappy" was named 2018 Rolling Stone magazine song of the summer. In early 2019, the band undertook a tour of the UK and Europe supporting Death Cab for Cutie. Their second studio albumJump Rope Gazers was released in July 2020. The band is known for its use of vocal harmony, using the voices of all three band members. The Beths have received financial support from the NZ on Air and NZ Music Commission. In September 2015, the band received money to make the single and video for "Whatever" from NZ on Air. In May 2016, NZ on Air funded a video for "Lying in the Sun". Through their Outward Sound program, the NZ Music Commission funded three tours as part of their international music market development grants.
