HOFF ENSEMBLE was introduced as a heading for a project involving several Norwegian artists performing compositions by Geir Bøhren and Bent Åserud, from NRK TV series Jul I Bjåfjell and Jul I Månetoppen. Among the artists and musicians participating were Arild Andersen, Rune Arnesen, Børge Petersen-Øverleir, Helene Bøksle, Mathias Eick, Bjørn Eidsvåg. The music was rearranged for jazz ensemble and solists by Jan Gunnar Hoff (piano/leader) and resulted in Quiet Winter Night 2012 (2L/Universal), also named and released as Stille stille vinternatt, a highly appreciated album receiving a nomination for Best surround sound (Morten Lindberg) at the 55 US Grammy Awards.
In 2018 HOFF ENSEMBLE reemerge, this time with Jan Gunnar Hoff in a jazz trio setting with leading European jazz performers Anders Jormin (bass) and Audun Kleive (drums). The trio released their album Polarity on 2L, April 2018. A vinyl edition of Polarity was released March 2023.
Both albums by the HOFF ENSEMBLE share the same beautiful rendering of acoustic instruments recorded by (2020-Grammy Awards Winner) Morten Lindberg in Sofienberg church, Oslo. The lyrical jazz concept is a core in Jan Gunnar Hoff´s music and in his arrangements. The performances by jazz musicians including Hoff´s expressive piano, link Polarity (2018) and Quiet Winter Night (2012) together in the same musical universe.
