«Andreas Ihlebæk has rapidly become one of the most dynamic, ground-breaking composers in modern classical music», wrote Apple Music after the release of Ihlebæk's album I Will Build You A House. Already his debut album The Guest (2017), which was hailed as "a masterpiece" in media all around Europe, put Ihlebæk on the international map as an innovative composer who had created a whole new genre of music.
 
With his unique blend of modern classical, soul, art pop, jazz, choral music and folk music from his native Norway, Ihlebæk captured listeners around the world, and each live concert became an event. "Andreas Ihlebæk's concert at Oslo Concert Hall was the musical highlight of the year", said Norway's national broadcaster NRK.

Through his collaboration with Marius Troy in creating immersive art experiences and installations, their HEKA Studio was in 2026 nominated for the Global Arts Prize for Innovation by the Global Leaders Institute, curated by Harvard, Oxford and Stanford University, among others. 2026 sees projects by the team in Seoul, Madrid, Paris and New York. Ihlebæk and Troy also collaborate on film music, and their debut film as co-composers Flophouse America has received a long list of prestigious awards internationally, and was also nominated for Amandaprisen (the Norwegian Oscars) in their native Norway. 

Ihlebæk's next album HEKA is set for release in 2026. This contains the piano music for the installation HEKA, an experience which "cured the writer's block" of one of Norway's premier classical music critics.

The album will first only be released on vinyl, with art work by Marius Troy. 
 
Ihlebæk has released four critically acclaimed solo albums – as of 2026. His latest album NOWHERE EVERYTHING again received overwhelming reviews and top scores from all around Europe, claiming the album was "one of the best albums of the year". It's been called a "otherworldly", "magical" and a "breathtakingly beautiful" work of "exceptional sophistication" that "it feels infinitely good to be in". Or as one critic put it: "If you're wondering what to listen to one last time before going deaf ...this is it". 

He was invited to perform the live finale at the Norwegian Grammies (Spellemannprisen) on NRK in 2021, filmed at the Norwegian National Museum – a performance which Spellemannprisen later presented as "the most beautiful moment of the year". 

Ihlebæk is currently dedicating much focus on his RO project.

In a time of increased separation, both from each other, nature and from ourselves, his aim is to create quiet and sacred spaces for people to go inward — together — in music. The word «RO» is old Nordic for calm, peaceful and freedom from distraction. Ihlebæk’s philosophy for the RO project is to quietly ask us to transcend our fear of stillness and inner reflection, and rediscover the often lost connections to our own remembrance that we are stronger than we know.  The project started in 2023 and has taken him around Norway. Since 2025 he has had a continuing residency at Gamle Aker kirke (the oldest building in Oslo, from the 1100’s), where he is developing the experience further and deeper. In September 2026 RObua (House of RO) will open in Engelsviken, Norway, where he and a team of co-founders are a building a physical space. They have taken over an old traditional rorbu in a fishing village, dating all the way back to the viking age, and are transforming into a social wellness space, with saunas, social lounge with ocean view, music room, yoga room, infrared saunas and cold plunge. It is on a peer, and you can walk right out into the water. RObua Engelsviken is set for opening in October / November 2026.
