Oh, oh, oh! Can you point me at your source? /lazy

It was absolutely fantastic. I liked Schiff anyway, but I had no idea how truly talented he is until we saw him on stage. The play is marvellously layered - one of those things where you can read it in many different ways: he's immortal, it's himself he's looking for, it's allegory. And the telling is fragmented, rambling, recursive. (I wanted to buy a copy of the text, but it seems only to be available for extortionate sums.)
He changed over the course of the performance. Evolved. Everything about it seemed real. It's all a direct address to the audience, but the nature of the audience being addressed changes over the course of the play, and somehow you felt yourself to change as required. There were moments when the actual-audience responded as the text-audience because they were so caught up in it.

I have a google alert on Schiff, because I'd travel some distance and pay quite a lot to see him on stage again.

And having hijacked your Iliad enthusiasm: I do hope that it's something that comes to the UK; I'd definitely make an effort to see it.
