I know its not to most people's tastes here, but I saw Charlemagne Palestine perform a six-hour organ piece in a church in London a few years back. It was very powerful and very disorientating, I started having audio hallucinations after a while.
Anyway, at the end he took a few moments to speak to the audience and make some interesting points. Firstly, he wanted to point out that the sound he had generated was as vast and as loud, if not more so, than any other performance we had ever heard or were ever likely to hear and that this had all been achieved without a single bit of electricity. Secondly, he reminded us that a great many churches have these instruments, at least one in every city, yet they are generally inaccessible to performers and music lovers a-like. Ever since then I've been itching to hear another church organ performance. I know I could probably head down to the cathedral this easter sunday and catch a bit but the emphasis wouldn't be on the organ, it would all be on this jesus fella and that.
