Sven-Erik Bäck (1919-1994) was a Swedish composer and conductor with a profound impact on the 20th-century classical music scene, particularly within Sweden. Born in Stockholm, Bäck showed an early gift for music that would see him leave a lasting legacy as a composer of chamber music, choral works, and orchestral compositions. He was a dedicated teacher and member of the Monday Group, a collection of composers who sought to create a new Swedish music rooted in a contemporary approach but still connected to the nation's folk traditions.

Throughout his career, Bäck worked tirelessly to blend traditional folk elements with modern techniques. His compositions often reflect this synthesis, and he was acclaimed for his ability to create deeply reflective and textured works that remain approachable. Bäck's oeuvre includes notable pieces such as "Motetter" (Motets) and "Tranfjädrarna" (The Crane Feathers), which showcase his skill in choral and instrumental writing, respectively. The double release of "Bäck: Fågeln" (The Bird) can be seen as a testament to his enduring appeal and the continued relevance of his works today. In addition to his output as a composer, Bäck's contributions to Swedish music as a conductor and educator have left a legacy that continues to influence Nordic composers and musicians.
