"Torbjörn Zetterberg (born 10 May 1976) is a Swedish jazz musician (double bass) and composer, known from collaborations with Jonas Kullhammar.

Zetterberg attended Södra Latin och Fridhems Folkhögskola in Svalöv but was first recognised as bassist when he studied at Kungliga Musikhögskolan in Stockholm still very young. Here he studied bass under guidance of Jan Adefelt. Soon he joined drummer Fredrik Norén's band together with the saxophonist Jonas Kullhammar. Already at this point one could sense that he would become a prominent figure in the Swedish jazz scene. Now his name is firmly rooted in the vibrant progressive selection as the new jazz generation.

He went through a personal crisis and did not record as a bandleader for more than seven years. Zetterberg was uncomfortable with his career and in 2010 he decided to leave the urban life including his bass, and moved to a Buddhist temple. There he resided for a year and still spends half of his time there in 2016. This existential crisis led to the production of the album Och Den Stora Frågan ("And the Big Question" in Swedish) in 2014. Here he collaborated with well known musicians from his earlier career, like the Portuguese trumpeter Susana Santos Silva and drummer Jon Fält, known from albums with pianist Bobo Stenson's trio. The album is "charged with joyful urgency, shiny optimism and confident flowing energy, despite the doubts and uncertainties that accompany any creative, artistic process", the reporter of All About Jazz stated in 2014."
