The current issue of the American Record Guide (March/April 2008) contains reviews I wrote of concerts by the Portland Baroque Orchestra and Cappella Romana that took place at the end of last year. (The long lag time is due to the time needed to put a bi-monthly magazine like ARG.)
In Portland, you can get copies at Classical Millennium. This issue has over 525 reviews in all, although the vast majority are of recordings. At $8 per copy, the ARG is a pretty good bargain.
