Tropism is the name of a Canadian harsh noise band founded by "Tnon" and "Pleb" in 1994 in Hamilton, Ontario, Canada. Although not official members, Rich Oddie and Christina Sealey of the industrial band Orphx were important early contributors. As of 2006, there are over 200 Tropism "releases" which can be divided into three periods: early (1994-1995), middle (1996-1999), and current (2000-present).
