We went to the performance of Woyzeck at Deutsches Theater last night. They offer certain performances with English surtitles and I can recommend taking advantage of this. The translations are not the best but they are good enough to help non-German speakers follow the storyline. The upcoming performances with English surtitles are Dirty Hands by Sartre, Children Of The Sun by Gorki, and Capitalista, Baby!, based on the novel by Ayn Rand.
In the case of Woyzeck, the music was written by Tom Waits and the production was using the original English songs. Tom Waits' music fit the story and mood so well; I was very impressed. I'm not a Tom Waits fan per se but the Eastern European influence in the songs gave you an instant feel for the mood and setting of the play. Thoroughly enjoyable.
