In Sotto Voce

In Sotto Voce was a secret side-project of Jo Casters & Herman Gillis from the band Poésie Noire, who started this secret side-project in 1988 as a response to a Belgian critic who found Poésie Noire "too poppy".
In Sotto Voce were supposedly two Yugoslavians named Ilya Dimitrijevic (Jo Casters) responsible for vocals/guitars and Boris Mikulic (really Herman Gillis) who handled keyboards and electronics. The two supposedly met each other at the University of Ljubljana where Ilya studied social sciences and Boris computer sciences.
