We just finished our first day of recording and my brain is toast. I do like recording a lot - there's something very positive about being able to go back and improve things that could have been better. That said, with six of us there's not much room to make mistakes either - it might be someone else's best go at a certain passage.
It's hard to keep the energy up all day too - in a concert you can give your all knowing that after roughly an hour and a half you can stop and relax. Today though we worked for around nine hours and by the end we were all fairly incoherent.
Organ verdict: Out for 2 pieces, 2 pieces with just the quiet wooden pipes, 3 left with the Principale and possibly wood or 4 ft too. Did I say incoherent?
