The Situationists, following their transition from an avant-guarde group of artists to a political organization, were archetypal councilists- arguing against the creation of permanent revolutionary communist organizations (they criticized every single tendency then extant, from trade unions to student groups to Maoists to left communists). They did have very lucid insights throughout the life of their journal (Internationale Situationniste), very penetrating critiques of USSR or PRC linked ideologies, groups and bureaucracies (such as critiques of the GPCR/Cultural Revolution, changes in the Eastern Bloc with the Prague Spring in 1968, etc.) and many relevant political ideas (Society of the Spectacle and On The Poverty of Student Life, not to mention The Beginning of an Era are all excellent texts).
Honestly I don't think a lot of their dynamism lies in the artistic experimentation period, but in the political period until their dissolution- where they were thoroughly councilists.
