When Goteborg Jazz Orchestra (GJO) - and the founders Mats Eklund and Johnny Olsson - laid out plans for the band's Monday night concerts for 2021 they came up with the concert series "Swedish Jazz Heroes", playing the music and telling the story of the role models who have shaped Swedish jazz of today. They came across the trombonist Eje Thelin and his last work, the suite Raggruppamento. The suite was firts performed and recorded live by the Radiojazz gruppen (RJG) in 1989 in the presence of Eje, but since he himself was too ill, he chose to let guitarist Goran Klinghagen play his feature parts and solos.
