With his cerebral, atmospheric style that belies a palpable inner passion and an inclination toward genre-crossing compositions, Bjørnstad helped develop and popularize the "European jazz" aesthetic. He is also a writer and poet and has published over 30 works beginning with his 1972 poetry collection Alone. Born in Oslo, Norway, Bjørnstad studied classical piano in London and Paris before making his debut in 1969 at age 16 with the Oslo Philharmonic Orchestra playing Béla Bartók's third piano concerto. Surrounded by the vibrant arts scene in Oslo during the '70s, Bjørnstad became interested in jazz and developing his own style of music. Citing an array of influences from Bach and Ravel to Thelonious Monk and Miles Davis, Bjørnstad began working in an improvised idiom. In 1973, he released his debut album Åpning featuring what would become a core group of longtime associates in drummer Jon Christensen, guitarist Terje Rypdal, and bassist Arild Andersen. The album would be the first of several outings Bjørnstad would record for Phillips. Over the years, Bjørnstad's particular mix of jazz, classical, folk, and rock music would become highly influential in the development of what became known as "European jazz." Although he has become well-associated with the premier European jazz label ECM, he did not record for the label until later in his career with 1993's Water Stories, 1994's The Sea, 1997's The River, and 1998's The Sea II. In 2000, Bjørnstad released the duo album Epigraphs with cellist David Darling on ECM. That same year, he composed the millennium oratorio "Himmel Rand," featuring the texts of the poet Stein Mehren. In 2002, he released the cinematic soundscape album Before the Light on Universal. In 2004, Bjørnstad released the rock-oriented Seafarer's Song featuring his ensemble with vocalist Kristin Asbjornsen. Four years later, he returned to ECM for the concert album Live in Leipzig with guitarist Rypdal. In 2008, Bjørnstad once again worked with drummer Christensen as well as tenor saxophonist Tore Brunborg for the ECM release Remembrance. In 2011, Bjørnstad delivered the duo album Night Song with cellist Svante Henryson on ECM. The pianist, who is also a published poet, novelist, and essayist, has stated that the Italian filmmaker Michelangelo Antonioni was one of his greatest influences; to that end, he composed a series of works meant to act as "a soundtrack to an inner film." Recording with bassist Arild Andersen percussionist Marilyn Mazur, cellist Anja Lechner, Eivind Aarset on guitar and electronics, and saxophonist Andy Sheppard, Bjørnstad released the live suite La Notte in the late spring of 2013.

2014 proved prolific for the composer and pianist. His first release of the year, appearing in March, was a 2012 recording entitled Sunrise: A Cantata on Texts by Edward Munch, performed by the pianist, his quartet, vocal soloist Kari Bremnes, and the Oslo Chamber Choir under the direction of conductor Egil Fossum. The musical work was set to surviving written texts by the famous painter. In October of that year, ECM also released the 2012 premier performance of Bjørnstad's A Passion for John Donne, a work based on the poet's life, commissioned by the Oslo International Church Festival, and performed live with the pianist's group the Oslo Chamber Choir under the direction of Hakon Daniel Nystedt. Interestingly, it featured the saxophonist Hakon Kornstad in a dual role, not only playing his horn but as a vocal soloist. ~ Matt Collar & Thom Jurek
