Barangaroo by Sebastian Sequoiah-Grayson
Several years ago I took a field recorder to several constructions sites around Sydney Australia. I transcribed the audio recordings I made into graphic notation. I then used the resulting graphic charts as improvisation platforms. This piece is from the Barangaroo construction site. I have been saving it and I have never improvised from it before (although I did transcribe it some time ago).

Sebastian Sequoiah-Grayson is a fingerstyle noise guitarist from Sydney.
