Intermediality as a theoretical and methodological perspective champions impurity. Overall, it is concerned with the interaction, contamination, and mixture between different media, breaking down existing barriers that currently exclude hybrid forms of artistic expression, which also inevitably exposes the limits of media specificity. Musical performance constitutes a privileged space to reflect on intermediality. It brings in not only music, but a mixture which includes literature, theatre, dancing and even painting and architecture. Music performance calls for all these artistic practices and articulates them through the song. Then, when it is filmed by a camera and recorded with microphones to be exhibited on a screen, new layers of meaning are added. This Alphaville issue is concerned with the performance of the intermedial in Brazilian cinema through music performance. It is an output of the project “Towards an Intermedial History of Brazilian Cinema: Exploring Intermediality as a Historiographic Method”, a shared endeavour by the University of Reading and the Federal University of São Carlos which was developed between 2015 and 2019, funded by the Arts and Humanities Research Council (AHRC) in the UK and the São Paulo Research Foundation (FAPESP) in Brazil
