The Avery Fisher Artist Program presented its annual Career Grants this year to the Dover Quartet; pianist Haochen Zhang, a native of Shanghai now living in Philadelphia; and American violinists Chad Hoopes and Stephen Waarts. The three soloists performed at New York’s Jerome L. Greene Performance Space in the awards ceremony on March 15. The quartet, a Philadelphia-based ensemble then in the midst of a European tour and performing in Salzburg, was honored in absentia.
