This summer, Jacob Mühlrad was hailed in the world's largest music magazine, BBC Music, when they gave his latest album, Time, top marks.

Tonight, the composer premieres his first major orchestral work, Rems, at the Concert Hall in Stockholm.

A work he has worked on for almost two years.

- To go from this idea to actually hearing an entire orchestra, over 50-60 people put this together.

It is a feeling of unreality, says Jacob Mühlrad in Morgonstudion and continues:

Works with world conductor

Working on a work for such a long time and then letting it go for someone else to manage it, Jacob Mühlrad describes as a kind of separation anxiety.

But he also says in Morgonstudion that he is happy to collaborate with such competent people and that he knows that the work is in good hands.

Rems will be conducted by world conductor Pablo Heras-Casado and performed by the Royal Philharmonic Orchestra.

- It's almost like an abstraction of the music.

As an architect who makes a detailed description of his skyscraper.

But it is not the architect who builds the skyscraper, says Jacob Mühlrad and continues:

- An orchestra is not just a lot of people, it is an instrument consisting of these fantastic individuals.

It is a very special feeling to write for a collective of people.

That's when you notice that we humans are absolutely fantastic when you work together.
