One of the people I spoke to at the excellent free concert at the National Gallery on Sunday was Dieter Lehnhoff, who completed his doctoral work at Catholic University shortly before I began mine. As it turns out, he is back in Washington this week to give a concert this evening, November 10, at 6:30 pm, with his group Ensemble Millennium. On the little-known concert series from the Inter-American Development Bank, they will perform some of the cantatas and other sacred works that Dr. Lehnhoff has just discovered and transcribed. The program is called Baroque Music from the Guatemalan Highlands, and it will be presented in the IADB's Enrique V. Iglesias Conference Center, at 1330 New York Avenue NW. This event is FREE, and no ticket is required. Sadly, I cannot attend myself, and I have not lined up anyone who might give us a review. If anyone reading this hears this concert, let us know what you heard.
