Gorecki's String Quartet No. 3 is a lengthy work of emotional color tempered with maturity, recorded by Kronos Quartet for the first time ever. Float on the second movement's buoyant, contemplative melody. Get thoughtful with the closing, somber harmonies, paced like calm respiration. Its title, "Songs are Sung," is after a line from a Russian poet who wrote, "When people die/ Songs are sung." Considering it was composed in 1995 and only released now, let it be hoped the 74-year-old Gorecki isn't trying to tell us something.
