The closing sound of the Foghorn Requiem as the Souter Foghorn sustained a note, until it exhausted its entire reservoir of air. This sound is recorded without compression so you can hear the full dynamic range of the performance. (www.sarahangliss.com/misc/foghornrequiem). Recorded by Sarah Angliss, Saturday 22 June 2013.

• Sound artist and radio producer Robin the Fog has also posted some great sounds from the day (sans tights), including his report for the BBC World Service.
