I adore the french Cavaillé-Coll instruments. Any organist will remember playing a Cavaillé-Coll for the first time. It brings the music to life in a whole new way. Daniel Roth is organist at Saint-Sulpice which is where Vierne was assistant organist a 130 years earlier. He's playing this music on the organ that Vierne would have played. It is incredibly exciting. We have such a wealth of coulour, we have these firy reeds, we have these beautiful open flutes, we have fizzy strings. I am going to play you the end of the finale from the 1st symphony, argueably one of his most famous works for organ. The reason I want you to hear this, is because the tension builds up, and up and up, and the very very very end of the entire thing is as if the whole world has fallen apart. You feel the entire space, you feel like you can see the building as you are listening. Yes, occasionally it's a tiny bit muddy, but it's such a huge acoustic, but that is what it is like to sit there and listen to the instrument. I think this is one of the interesting things when we are talking about organ recordings. You are always having to balance atmosphere versus clarity. And the reality is that if you're sitting in a cavernous space you are not going to get total clarity the entire time and that's okay!
