Lars Gunnar Victor Gullin (4 May 1928 – 17 May 1976) was a Swedish jazz baritone saxophone player, occasional pianist and composer closest in playing style to United States Cool school players, with a full tone, but also a lightness uncommon with baritone saxophonists and an influence from Swedish folk music, which helps make his music unique.
Lars Gullin was a child prodigy on the accordion. At age thirteen, he played clarinet in a military band and later learned the alto saxophone, but after moving to Stockholm in 1947 became a professional musician as a pianist. He planned on a classical career, studying privately with classical pianist Sven Brandel. Although he actually filled the baritone chair in Seymour Österwall’s band in 1949 by chance, it was enough for him to decide that it was an instrument with possibilities, influenced too by hearing the United States baritone saxophonist Gerry Mulligan for the first time on the Birth of the Cool recordings. He worked as a member of Arne Domnérus’s septet (initially co-led by the trumpeter Rolf Ericson) for two years from 1951; the group mainly performed at Nalen, a leading dance spot in Stockholm.
