In 2007–2008 artists Duncan Whitley and James Wyness took a trip to Seville and made multi-channel recordings of the Holy Week processions there, which involve 58 Catholic brotherhoods plus floats and brass bands. Whitley and Wyness then mapped the recordings, and developed them into a large scale sound installation in the crypt of St Pancras Church.
Now Whitles and Wyness are publishing a PDF book with embedded audio recordings of the project, titled Listening Through Holy Week. The book includes 12 recordings, maps, essays and photos, and can be downloaded via Issu and Scribd (it's also published in Spanish).
The entire collection of recordings has been archived as part of the British Library's sound collection (reference C1338), and SoundFjord is currently in the process of developing an exhibition and events series (with ethnographic film screenings). The series will run alongside Whitley's project, and use files sent back from his trip to Seville in Easter next year. More info on the SoundFjord project in the coming months.
