Bellows is the bedroom recording project of songwriter and producer Oliver Kalb. The sound of Bellows is sensory and delicate, subtle and quiet, but erupts with frantic wobbling drums, large orchestral sections and bursts of noise that push the conventions of pop and folk. Started in late 2010 in a bedroom in upstate New York, Bellows has since blossomed from a solo recording experiment into a large-scale rock band, employing the help of friends to bring Kalb's intimate home recordings to life on stage in sweeping, loud, and intense live performances.

Bellows’ sonic palate has developed and grown considerably across five albums released over the last decade. Bob Boilen of NPR’s All Songs Considered named Bellows sophomore album Blue Breath one of his favorite albums of 2014. Two tracks from Bellows’ electronic-inflected third album Fist & Palm were included in Stereogum’s Best Songs of 2016 list. The Rose Gardener was included in Paste Magazine’s Best Overlooked Albums of 2019 list. Bellows’ latest, the mammoth double-LP "Que Bello!" arrives in June 2026.
