press play at the cac

I finally received all my videos from the CAC event. Yahooooo! And here is a performance of "Press Play." Guess what? You can see it! And you can see the tape players! And, honestly, this is the best performance of this piece yet.

So a question to you folks: is this a fixed-format piece, live performance, or a sound installation? I haven't quite decided the format of this piece. I had a friend suggest that the tape players should be on display in a room so people can have the freedom to walk around and hear it. I also think it's fun to have a vintage tape recorder on your lap while you "perform" your part. Thoughts? Suggestions?
