On January 10-13, 1999, an ICTM Colloquium was held in Visby, Sweden, sponsored by the Swedish committee of the ICTM as part of the long-term research project “Musik-Medier-Mangkultur” (Music, Media, Multiculturalism), directed by Krister Malm and Dan Lundberg. I was one of the participants, along with the following cast of characters: John Baily, Dieter Christensen, Beverly Diamond, Salwa El-Shawan Castelo-Branco, Eva Fock, Josep Marti i Perez, Pirkko Moisala, Pieter Remes, and from Sweden, Hans Huss, Henrik Karlsson, Dan Lundberg, Krister Malm, and Owe Ronström. Presenters were asked not to give formal presentations, but rather thematic introductions to extensive discussions, which were taped and transcribed. Malm and Lundberg later created diagrams and tabulations of the terminology introduced and the concepts raised by the sessions, and asked me to use the conference papers and discussion as a springboard for addressing the issues raised at Visby.
