As an electric, acoustic, and 11-string alto guitarist, he has performed at festivals and concerts throughout Europe and North America. His solo guitar music is featured on the albums Night Guitar (2012) and Äventyr (2022).

“Anders Nilsson, a guitarist-composer comfortable with everything from free improvisation to avant-garde metal, celebrates a fine recent solo effort, Night Guitar, that traverses ghostly mood-setting, bluesy twang and overdriven riffage.”  – Time Out, New York.

His own band Hesa Gun features his own compositions together with Sam Kulik – trombone, David Ambrosio- bass, Vinnie Sperazza – drums. He plays on over 40 albums and has performed and/or recorded with many artists such as Mohsen Namjoo, Gordon Beeferman, Jason Kao Hwang, Kalabalik, Paquito D’Rivera, Elliott Sharp, Fay Victor, and Angelblood. Nilsson’s work as a composer has produced 100+ compositions ranging from brief to epic solo works to large experimental ensemble works, many of which have been released on several acclaimed albums. He has also written music for string quartet, short films, butoh dance performances and theatre.
