Anders Hillborg gained his first musical experience singing in choirs and he was also involved in various forms of improvised music. From 1976 to 1982 he studied counterpoint, composition and electronic music at the Royal College of Music in Stockholm, where his teachers included Gunnar Bucht, Lars-Erik Rosell, Arne Mellnäs and Pär Lindgren. Brian Ferneyhough, who was a guest lecturer at the College of Music on several occasions, was also an important source of inspiration.

Apart from occasional teaching positions, Hillborg has been a full-time freelance composer since 1982. His sphere of activity is extensive, covering orchestral, choral and chamber music as well as music for films and pop music.
