Ryan and I have been looking into slow-developing, textural music (a definite shared interest of ours), so to research a bit I tried to find live performances of a number of artists I love who create music through similar means. Small numbers of musicians but large sound worlds. Accomplishing this either through performing on multiple instruments, looping, smart orchestration, or whatever other means.
The first artist I went to is Kishi Bashi. He is a singer/songwriter/violinist I have loved for a long while. I've seen him live twice, and both times he played with a band, but I remembered one of my friends from home mentioning to check out his solo stuff. He performs with just his violin, a pedal board, and his voice, and wow. Very intelligent use of the sounds available to him, fantastic orchestration.
A second group I looked to, which Ryan and I spent some time listening to last week is Beach House. They're already a massive inspiration of mine, but I've (once again) never consumed any of their live material. This video does a job of displaying just how many layers of texture each member of the live band is responsible for. If we were trying to do something along these lines, but without a third person, it would require the use of significant drum looping, but I think that would be very doable given our access to hardware and software.
For our video component, I spent some time researching locations we could access public domain footage to use for one component of the display. I found a number of sources, both on youtube and in websites, and began browsing through them. Here is one notably fantastic piece of public domain footage I found: The Private Life of a Cat.
