Two interesting stories from today’s Weekend Edition Sunday:

- Did you know that pipe organs can be a source of pollution? Organ builders in the European Union are having to search for different metals to build their pipes with as a mean of adapting to a new EU environmental directive aimed at reducing the amount of lead in electronic devices.

- What side of the authenticity argument does Norwegian baroque guitarist Rolf Lislevand come down on? His new CD Nuove Musiche, which features percussion, theorbo, clavichord, nyckelharpa, and a jazz-tinged double bass as the back-up band for vocalist Arianna Savall should be an indication.
