As a member of Crowded House, Seymour provides bass guitar, backing vocals and song writing, as well as artwork for album covers, costumes and stage sets. With their second album, "Temple of Low Men" (July 1988), he won the ARIA Music Awards of 1989 category for Best Cover Art. He was nominated for the same award for "Crowded House" (June 1986) in 1987, "Woodface" (July 1991) in 1992, and "Together Alone" (October 1993) in 1994. In early 1989, after a tour of Australia and Canada, Finn fired Seymour from Crowded House. According to music journalist, Ed Nimmervoll, Seymour's departure was due to Finn blaming him for causing the latter's writer's block. However Finn cited "artistic differences" as the reason. Seymour said that after a month apart, he contacted Finn and they agreed that he would return to the band. He subsequently stayed with the group until their disbandment in 1996.
