CASEY FARINA: Well, I had a bunch of people composing music. It was myself, Chris Mercer, Steve Syverud, Theron Humiston, Brett Masteller, and Jonathan Kirk all composed music for the project. Everybody sort of made their own decision about how to utilize the sound system. Usually, when you’re mixing something for eight channels, it would be in some sort of set configuration, but here people were deciding whether or not to dynamically spread sounds around or sort of keep sounds in certain speakers but then move the blimps, and so that was each composer sort of made their own decisions about that.

And so we had -- What is that?-- seven pieces, and we sort of played them back to back with whatever they wanted the blimps to do.

GRETCHEN HASSE: Okay. So, each composer controlled their own piece as it came up?

CASEY FARINA: Yes.

GRETCHEN HASSE: Okay. I got it. And they used the same stuff that you were working? How did they work? Pardon me for not understanding what you just said. They were working it from the same setup that you had like sending speak -- sending?

CASEY FARINA: Sure. All of that was set by the time the performance happened.

GRETCHEN HASSE: Oh. Okay.

CASEY FARINA: So, essentially we were just playing back their pieces. It may have been already determined how they wanted everything to happen.

GRETCHEN HASSE: So, they’re programmed. How did it work with the trombone, with the different live instruments?

CASEY FARINA: With the live instruments, we were taking the input from the microphone, which was running through an additional computer where we’re doing some eight-channel spatialization, so we’re sending the channel -- sending the sound to different blimps dynamically...

GRETCHEN HASSE: Mmm hmm.

CASEY FARINA: And then as part of the sound system, so we had an additional computer where we’re sort of processing the sound and trying to create some sort of dialogue between the live player and the blimp system.
