Linnea Andreassen is a swedish mezzosoprano from Uppsala now situated in Stockholm.

Current and forthcoming appearances include Britta and Jordemodern in Ture Rangströms Kronbruden at Malmö Opera, Vetenskapen in the newly written Ålevangeliet at Folkoperan Stockholm, and on tour, Andronico in Vivaldi's Il Giustino at Drottningholm Palace Theatre, and Oxygeni in The Tale of the Great Computing Machine for KTH/Vadstena Academy. 

She is educated at the University College of Opera and the Royal College of Music in Stockholm where she studied singing for Erik Årman, who she is still studying with.

Linnea made her debut in 2015 as one of the three Adelige Waisen in Christof Loys production of Der Rosenkavalier at the Royal Swedish Opera in Stockholm. At Malmö Opera she made her debut in spring 2017 portraying Der Trommler in Viktor Ullmans Der Kaiser von Atlantis - a role she portrayed not only with her voice but also by playing the marching drum herself. In the summer of 2018 and 2020 she returned to Malmö Opera to perform the role La Feminste Atheé in Isabell Aboulkers opera Surprises de l'Enfer.

The Mezzosoprano Linnea Andreassen as Der Trommler is a wonder of sharpness as well as a singer, a physical actor and a drummer. Better casting couldn't have been done.

Linnea is a sought for soloist in both standard repertoire and contemporary music and she has performed numerous world premieres. In 2021 she appeared  in the world premiere of the Icelandic composer Karólína Eiríksdótter's newly written opera BLY at Piteå Kammaropera in autumn 2021. In August 2018 she performed as The Squire Jöns in the world premiere of the Brazilian composer João Mcdowells opera The Seventh Seal based on Ingmar Bergmans movie with the same name. The opera premiered at the Bergman Festival in Stockholm and was later on performed in Tatuí and Ilhabela in Brazil. During 2019 Linnea performed as the only singer in the Swedish premiere of the Dutch composer Leonard Evers children's opera Gold, at Teater Pero in Stockholm and later on in the world premiere of the Swedish composer Jonas Forssells opera Memory for Estrad Norr where she performed one of the leading roles.

Linnea is also an acknowledged interpreter of baroque music and in the summer of 2019, she performed the role Antiope in Maria Antonia Walpurgis' Talestri, Regina delle Amazzoni with the free opera companies Kamraterna and Den Andra Operan - one of the first performances of the opera since its world premiere in 1766. To be able to continue her studies in earlier music she was the first to receive Vännernas Opera Scholarship from the Friends of Drottningholms Slottsteater in 2018. The scholarship was awarded by his majesty Carl XVI Gustaf king of Sweden during a concert at The Drottningholm Court Theatre.

Linnea discovered opera at an early age when she visited the Royal Opera in Stockholm for a performance of Mozart's Die Zauberflöte at four years old. After that she knew that she wanted to become an opera singer when she´ll grew up and often entertained her peers at the kindergarten performing as the Queen of the Night from her favourite climbing tree. At 8 years old Linnea formed her own amateur theatre group - an initiative that was about to last until she was 16 and was a platform where she further discovered her love and talent for working on stage. Her musical development Linnea found in a lot of different choirs and pop bands in her youth until she finally decided that the right path for her was to fulfil her childhood dream to become an opera singer and she started to study classical singing in 2008.

Linnea finished her studies at the University College of Opera in Stockholm in 2017. During her studies she worked on roles such as Nancy in Britten's Albert Herring, Sesto in La clemenza di Tito by Mozart, Rosina in Il barbieri di Siviglia by Rossini, Anna 1 in Die Sieben Todsünden by Weill and Dinah in Trouble in Tahiti by Bernstein.
