The Suffolk Symphony is an old-school take on locational art — no snazzy geocoded uploads, no virtual-environment overlays. It’s an audio-visual construction based on materials from a specific place, in this case Aldeburgh. The materials — sonic and visual — were collected in a week by noted figures associated with the Touch record label: Philip Jeck, BJNilsen, Jon Wozencroft, Philip Marshall, and Mike Harding. They’ve posted a rehearsal recording of what is to be performed live on August 22. It’s a sprawling piece (MP3), to say the least (the recording is audio-only), with opening timpani and strings making the “symphony” aspect feel real, but with electronic effects, field recordings, and an overall lush minimalism eventually subsuming the more traditional orchestral patterning.
