Angel Perez Grandi, who has contributed some stunning Argentinian field recordings, chose this theme. In his words:
My suggestion for a set would be “natural echo spaces”, that is, spaces or sounds with inherent (natural) reverb. Diffused, decay, blurry background activity are words that pop to my mind. From canyons to temples to claustrophobic spaces as long as we get a strong sense of space. The resonance can be forced but not created through processing – a loud bang inside a tank would qualify too for example.
So; echoey sounds in a variety of interesting acoustic spaces – exterior or interior. This could include anything from footsteps in a stairwell to voices in a cathedral to gunshots in a valley to door slams in an industrial lift. As is often the way with my briefs, the main requirement is ‘character’. Can’t really add much to that – sounds like a great theme choice to me. Enjoy!
