The designation of the black metal sound as “lo-fi” by academics is problematic,since it doesn’t reflect the contemporary black metal production. Fieldworkin the Québec scene show that the members designate their sound asbeing “in the middle” – or mid-fi as I advocate it. In this paper, I first define“hi-fi”, “lo-fi”, “authenticity” and “mid-fi” in the context of black metal.Then, I present different black metal sound aesthetic using audio extracts,frequency analysis, spectrogram images and ethnographic data. This analysisallow better qualify black metal aesthetic production today using the Québecscene as an example.
