Kalbells is the solo project of Rubblebucket frontperson and lead singer Annakalmia Traver. Following its conception, Traver pulled on her former touring musicians Angelica Bess, Zoë Brecher, and Sarah Pedinotti, and formed a proper band to perform and create with.

Proudly wearing art-pop, synth-pop, and jazz influences, the group’s 2017 debut album, Ten Flowers, initially served as a cathartic response to Traver’s recovery from cancer. Despite that, Kalbells' music often highlights playful lyrics and humorous themes, evoking memories of youth and growth.
