Can anyone identify this lunchtime concert work?

This suggests there were four movements as you have them.

Wow!

Very many thanks for finding this. It looks as though the first movement of the work got lost when processing the recording. I have: 'A day without yesterday', 'Black rain', 'Einstein cross' and 'Internebula' as stated by the announcer. Have you any idea what the first movement is called? I've searched and cannot find a listing.

Those titles match the four movements as announced:

• A day without yesterday - which begins with a single line
• Black rain - a pizzicato dance
• Einstein cross - a reference to a gravitational illusion where a galaxy hides itself behind another and becomes more visible
• Internebula - and here, harmonic fragments hurtle through space apparently out of control

Here's the introduction, inc. a brief one by Deirdre Gribbin.

French Frank's notes are very helpful.
This interview might also add some background.
