Another weird day at work.

Turned up at work today to discover we weren't working in the concert hall we usually work in but next door in the Grass Market. Always an ominous sign. We only ever play here for seriously weird stuff. And sure enough here is what was on my stand. It is, believe it or not the score for the piece we're playing this weekend.
Having seen the banks of loud speakers opposite us I thought it prudent to get my ear plugs out.
