Sound of Imagination
The Last Echo
The repeat after the source has left the street
Key art
The room the tone keeps
The Last Echo is the repeat after the source has left the street. The film is Your Horse Already Left: the street is still an audience, the horse has reviewed the show and walked. He says it comes back. He pays better.
What the frequency does
Leo will perform for a crowd that has started to be a rumour. The echo is what the score keeps, because the animal has already given its notice.
After the last bar
The horse is still gone. The film plays this and links here.
