Fred Anderson (March 22, 1929 – June 24, 2010)[1] was an American jazz tenor saxophonist who was based in Chicago, Illinois.[2] Anderson's playing was rooted in the swing music and hard bop idioms,[3][4] but he also incorporated innovations from free jazz.[4] Anderson was also noted for having mentored numerous young musicians.[5] Critic Ben Ratliff called him "a father figure of experimental jazz in Chicago".[6] Writer John Corbett referred to him as "scene caretaker, underground booster, indefatigable cultural worker, quiet force for good."[7] In 2001, author John Litweiler called Anderson "the finest tenor saxophonist in free jazz/underground jazz/outside jazz today."[8]
