OPA (Obsessive Possessive Aggression) is a collaboration founded in Skopje in 2001 by the visual artists Slobodanka Stevceska and Denis Saraginovski. OPA’s practices are context based, non-collectible and either ephemeral or distributed in multiple copies. Its works have been shown widely in group exhibitions and festivals such as Transmediale, Berlin; Biennale of Contemporary Art, Moscow; Transeuropa - European Theatre- and Performance Festival, Hildesheim; Autostrada Biennale, Prizren, etc. (www.o-p-a.org)
