Inspiration quite frequently arrives as a surprise. The key is being open to it.
In order for my live performance to work, which is about generating a focused energy for about an hour and a half, it is necessary for me to listen and take in someone else's focused energy the day of or the day before the live show. That can transpire through a conversation, or inspiration can occur by looking through any type of visual book which sparks a narrative. That narrative then becomes today's seed and can then take root in music terms, where a sonic tree begins to grow.
Sometimes you need to take a departure from what you do to something that's slightly different in order to get inspiration.
