Concerning the poetry, I enjoyed it a lot, actually. I don't have much to say because I left it at school, but from what I remember, the poems appealed to me like my own song-writing. When I write, I tend to take a bunch of images and thread them along together in a way that makes sense to me. I remember reading the first one and thinking "I could have written that". That said, I think the poetry was expressionist because all of the images in the poems were some description of feeling of emotion.
The operas and dance pieces seemed very impulsive and on-the-spot. The dances, especially, look like choreographed improv pieces. Everything is very sensual and non-linear. None of the dance pieces seemed to have a methodical structure at all.
I'm not sure where the themes of death or the speed of each piece plays into expressionism, but I guess I'll find out later.
