Helge Lien
jazz pianist and composer, holds a master degree in music from the Norwegian Academy of Music, where Russian pianist Misha Alperin was an inspiring mentor and teacher of improvisation.

The core of Lien’s work has since 1999 centered on the Helge Lien Trio, consisting of the classical jazz constellation piano, bass and drums. In 2008 the trio won the Norwegian Grammy for their album Hello Troll, and has achieved international acclaim following tours in Japan, Germany and Canada, among other places.

With Tri O’Trang (1998–2006), consisting of piano, saxophone and tuba, Lien has cultivated a more structural music with strong melodic as well as abstract features, in which composed and improvised elements are interwoven.

The duo HERO (2005–6), with saxophonist Rolf-Erik Nystrøm, focused on “contemporary music,” emphasizing atonal and arhythmic elements and extensive experimentation with timbre. During this period, the two musicians participated in folksong artist Jørn Simen Øverli’s project Prøysenvisene som forsvant (The Prøysen songs that disappeared).

Helge Lien has shown himself to be a musician who is not afraid to explore the borders between different musical genres, but whose basic sound as a jazz pianist is always a distinctive feature. Originally influenced by Bill Evans’ lyric-dynamic style of playing, he also shows affinity with Keith Jarrett’s narrative inventiveness and the subtle strophic expression of Brad Mehldau. Lien is a technically brilliant player, with a solid and rich sound. His resourcefulness and briskly responsive playing comes in extremely handy as a “composer of the moment” in all of his work.
