Salon des Refusés
From an academic perspective, many traces of transgression can be found in any art which by some is considered offensive because of its shock value; from the French Salon des Refusés artists to Dada and Surrealism. Philosophers Mikhail Bakhtin and Georges Bataille have published works on the nature of transgression. Probably the most thorough book on the early transgressive movement is "Deathtripping: The Cinema of Transgression" by Jack Sargeant.
