Chapter 4 details the structural arrangements that facilitated foreign travel to the Warsaw Autumn. It focuses on the non-performers who went to Poland to hear the festival concerts, either as invited special guests or as tourists. The chapter argues that these travelers’ journeys contributed to the circulation of information, ideas, values, financial assets, and objects that took place via the Warsaw Autumn; consequently, their journeys enabled the festival’s effects to extend far beyond Poland. Moreover, the festival’s foreign travelers served an economic function, in that they allowed composers and other players to mobilize resources, accumulate prestige, access new distribution channels, and expand their personal and professional networks. Drawing on work by Stephen Greenblatt as well as Steven Vertovec, this chapter introduces the themes of literal versus metaphorical mobility, and international versus transnational forms of cross-border contact, that will be important throughout the second half of the book.
