Swedish guitarist from Stockholm, born 1957. He is called Nysse.

In the mid-1970s, he played in the prog music group Råg i rygning and then switched to Strix Q when they were formed in 1978. Strix, (Uggla (Owl) in Latin) as the band was originally called, was formed after the autumn tour in 1977 with Magnus Uggla, as a backing band for Uggla.

In 1984 Nyström tried a solo career and Uggla then produced the single Jag villl ha mycke' pengar and En liten grej where Nyström sang a duet with Vicki Benckert. He has also played with Pugh Rogefeldt and Staffan Birkenfalk. With Birkenfalk, Nyström also has the group Good Clean Fun. In 2007, the Strix Q group was resurrected under the name strixq.nu.
