in 1998 under guidance of Mikhail Alperin, known as pianist of the Moscow Art Trio and from solo performances and recordings, and did postgraduate studies with the group Tri O'Trang culminating with cand.musicae exam in 2001.

Lien is known from a variety of musical contexts, such as Tri O'Trang (with Torben Snekkestad on sax and Lars Andreas Haug on tuba), Helge Lien Trio, the duo Hero with saxophonist Rolf-Erik Nystrom, and with the vocalists Live Maria Roggen and Silje Nergaard.

The last decade Lien has given us a lot of evidence that a new Norwegian pianist of a very high caliber has entered the Jazz scene.

We have encountered him in various constellations from solo piano, duos and as sideman, but it is first and foremost with Helge Lien Trio that he has moved up and out among the truly great.

With their seven albums and thrilling live performances they have already earned a large fan base, and when the Helge Lien Trio completed their first tour of Germany on the Berlin Jazz Club A-Trane in 2008, the album Hello Troll was the first Helge Lien Trio release for Ozella Music in Germany.
