An exotic group C*-algebra of a group G is a C*-algebra that lies naturally in between the reduced and the universal group C*-algebra of G. An existence of an exotic C*-algebra can be viewed in some sense as a refinement of the non-amenability of G. We will discuss several approaches to construct such algebras and then will describe a family of exotic group C*-algebras coming from the family of groups without free subgroups.
