Can anyone recommend ways to reserve/buy tickets from the US for concerts at Notre Dame, Saint Chapelle etc in Paris?
Maybe this link will help, it gives 2 websites that may also offer tickets for what you're looking for:http://www.ricksteves.com/graffiti/helpline/index.cfm/rurl/topic/23586/opera-de-paris.html
I JUST was in France (mid Oct) and went to a fabulous concert at St Chapelle. Just showed up a hour before (for mine, 30min would have worked too) and bought tickets (about 25 euros)
It was expensive, but you couldn't beat the location or sound. It was just a treat!
We purchased our tickets here for a Sainte Chapelle Concert last year

Les Archets de Paris performed and were Outstanding !
At least at Notre Dame, finding out about upcoming concerts is quite easy. There are posters in front of the cathedral advertising events with the dates and times. We went to an evening Gregorian chant concert in September. Although we pre-purchased our tickets in the morning inside Notre Dame at the information booth, that wasn't necessary because most folks just showed up before the concert and bought their tickets on the spot. Notre Dame during the day with the crowds is an amazing experience. Notre Dame at night with its wonderful acoustics is unforgettable.
