This Estonian composer has made a rare trip to the States to hear this concert, produced by the St. Vladimir's Seminary. On the program are some of Mr. Part's greatest hits - including "Fratres," "Cantus in Memoriam Benjamin Britten" and "Adam's Lament" - performed by some of his greatest interpreters, the Estonian Philharmonic Chamber Choir and Tallinn Chamber Orchestra. Tonu Kaljuste conducts.
