Sweet Insanity is an unofficial album by American musician Brian Wilson that was produced in 1990 as the follow-up to his first solo album, Brian Wilson (1988). It was largely written and produced by Wilson alongside his former psychologist, Eugene Landy. The album was rejected by Sire Records due to Landy's lyrics and the inclusion of "Smart Girls", a rap song. Select tracks were later rerecorded for Wilson's 2004 album Gettin' In over My Head.
