'diabase intrusive or extrusive' is an ongoing research project by David Addison stemming from the initial question: which two pieces of music would you like played at your funeral?
Submissions will be compiled and aim to inform a visual art project in 2018. Possible outcomes include a public exhibition, critical text(s), digital archive, printed publication or presentation within an audio format.
Please share with anyone you feel may be interested or benefit in somehow from tackling the question. A varied dataset of ages, locations, gender and cultural identities will help realise a more fully formed response and critical understanding. If you would like to discuss any aspects of the project in further detail then please get in touch at email@example.com
All submissions can be made anonymously, if contact details are provided then any personal data will be stored securely and if presented publically you will be consulted for consent before any distinguising information is released in a public facing format.
A 'song' here is defined as any piece of recorded music or other composition of sound, instrumental or otherwise. Please supply the performer(s) of your chosen version of the piece rather than original writer if different.
