The night before I started to write this review, PBS began a five-part series on computers called "The Machine that Changed the World." The first episode described the development of the ENIAC (Electronic Numerical Integrator and Accumulator), the first electronic computer. The ENIAC used 18,000 vacuum tubes, had over 500,000 solder joints, required a room 30' by 50', had to be physically reprogrammed with patch cords to perform different tasks, and packed less computing power than today's $4.99 pocket calculator.

When do 12 hands + 12 eyes = boundless creativity? When you gather up the six New York-based composers of the highly heralded Sleeping Giant collective, set them loose in an extraordinary collection of contemporary art, and invite them to compose art-inspired music for four-time Grammy-winning Chicago new-music sextet, Eighth Blackbird. From this is born Hand Eye, a recording that opens the ear, eye, and mind simultaneously as it transport you to landscapes all their own. If you crave music that stimulates and provokes, you have to hear it.
