Basilica of the National Shrine of the Immaculate Conception, Washington DC, Dec 2007 The DC Boys Choir performed jointly with Moscow Boys Choir Capella. The DC Boys Choir only had about an hour to practice with the Moscow Boys Choir before singing together for the first time. Their performance was so spectacular that they impressed the Moscow Boys Choir and the their conductors. Below are words of appreciation from the Moscow Boys Choir Conductors to the DC Boys Choir.
