Mother of god, I saw the Carmina Burana performance last night at Benaroya Hall. It started off with a solo violinist, then intermission and then O Fortuna to start things off. Wow, that was awesome...
Basically 100+ people singing, three soloists, and the full orchestra. Throw in primo seating and I could've cried at various points, it was so vibrant and powerful.
So if this ever comes to your neck of the woods, go. There may be better versions on iTunes, but I bought the Boston Symphony/Ozawa version and it kicks butt. Nothing like the real thing though, props to all the performers last night.
