The duo collaboration of Marcus Wärnheim and Jonathan Bäckström is the fruit of a long friendship and musical companionship. As intimate as a confidential conversation, their music unfolds with precision and presence by remaining in the spectrum between low and ultralow dynamics. Their carefully constructed musical microverses utilizes the extended sound palettes of their instruments though breath, noise and consonance and invites the listener to an intense listening experience. Their debut album ett was self-released on the 31st of October 2025.

Jonathan Bäckström – double bass

“Bäckström and Wärnheim employ an array of extended bowing and breathing techniques that help them blend their ethereal, dissonant, and microtonal multiphonics into one, otherworldly sonic entity.”
