Stefan Wistrand got hooked on jazz in the early 70s and at the same time took up playing the saxophone. At first involved in the then-current jazz rock scene, he soon encountered free jazz through the duo he formed in the mid 70s with drummer Peter Olsen. In 1978 they released the album Duo on composer Leo Nilsson’s label Studio Viarp. Throughout the 80s Wistrand was active on the alternative rock scene, touring Sweden and Scandinavia and recording three albums with rock group Memento Mori.
In the 90s he returned to jazz and improvisational music and was initially mainly active as leader of free jazz group Nods Off, with Olsen, bassist Stefan Larsson and guitarist Daniel Berton. Nods Off has released five CDs on Einnicken Records. Other jazz musicians who have been members of Nods Off are drummer Erik Dahlbäck, bassist Tommy Skotte, trumpeters Tommy Adolfsson and Emil Strandberg.
In 1999, together with musician Per Åhlund, Wistrand formed the musician collective and scene Memento in Eskilstuna. A coalition of creative musicians in the genres of electronica, jazz, rock and improvisation.
Wistrand started several projects with young musicians around the turn of the century 99-00, as for example jazz group Blue Room Repository Ensemble, big band Memento Creative Orchestra, free improvising units Fundamental Form and Two Sounds Ensemble.The latter, a duo with pianist Joakim Simonsson, has released two albums Inversions (2004) and Fictions (2009)
