On the morning of 15th April, Paul Sonderegger stepped off the Chicago red-eye to meet Dame Evelyn Glennie at her home recording studio.
Glennie, a Grammy award-winning percussionist and Sonderegger, a tech celebrity, were there to discuss "Big Data" and its surprising symmetries with the sonic world we inhabit, and yet ignore.
The conversation ranged from little-known concepts of data shapes, to how as a young musician Dame Evelyn dealt with losing her hearing.
This film captures the meeting of 2 legends; their conversation , understanding and subsequent composition.
