Tidings and Sediments is a piece by Grammy-nominated bassist, improviser, and composer Mark Dresser. He imagined a work where each performance would carry with it the residue of previous performances. To that end, after each performance Dresser would identify moments that he thought were particularly powerful or interesting. I would then use the audio and video recordings of those moments to compose electronic music and multimedia segments that would be included in the next performance. As an example, the manipulation I composed based on vocalist Bae Il Dong’s solo at the premiere served in the second performance as musical and visual counterpoint to an improvisation by Dresser.
