I saw Renascence last year. I would say I admired it more than enjoyed it. It was a story about the poet Edna St. Vincent Millay, with all the songs being her poems set to music. The last song was 20 minutes long, literally, because it is a long poem. It kept me engaged, I wasn't bored. As a matter of fact, I was quite impressed how Carmel Dean managed to write beautiful melodic songs out of poems without altering the text. Just checked Transport Group's archive page, they did quite some works from Michael John LaChiusa. So, I can't say if they usually do good productions or not, but they tend to do artistically challenging works.
