Former IMF chief Dominique Strauss-Kahn, battling attempted rape charges in New York, has attended two Boston Symphony Orchestra concerts at the Tanglewood Music Festival, The New York Times reported Saturday. The first concert was a recital by Danish violinist Nikolaj Znaider on Thursday at Tanglewood, a famed estate that hosts one of the world's premier music festivals every summer in the Berkshire Hills of Massachusetts and located 150 miles (225 kilometers) from Manhattan. On Friday Strauss-Kahn was back at the venue, the Boston Symphony's summer home, for a concert with conductor Kurt Masur and cellist Lynn Harrell, the paper reported. Strauss-Kahn had orchestra seats with his wife, the former French television journalist Anne Sinclair, who celebrated her 63rd birthday on Friday. The pair apparently declined to talk to reporters. The Times published a photograph of the two seated at the venue that showed Strauss-Kahn with a blue sweater casually draped over his shoulders, and Sinclair wearing a white blouse. Earlier this month Strauss-Kahn was released from house arrest, and the travel restrictions that confined him to a townhouse in New York were lifted, after US prosecutors raised concerns about the credibility of the New York hotel maid who accused him of sexual assault. But the charges made by the Guinean woman have not been dismissed, and Strauss-Kahn is due back in court on August 1.
