A ground-breaking collective of choreographers working in New York in the 1960s whose avant-garde work gave birth to the movement eventually known as post-modern dance. The first Judson performance was given on 6 Jul. 1962 at Judson Memorial Church on Washington Square in New York's Greenwich Village. The choreographers were united in their rejection of traditional form and technique, of narrative and overt theatricality, although they chose different ways of expressing their radicalism. Founding members included Lucinda Childs, Yvonne Rainer, Steve Paxton, David Gordon, and Trisha Brown; later came Twyla Tharp. One of the most important features of Judson Dance Theater was the collaboration of visual artists (such as Robert Rauschenberg) and composers who also made choreography.
