Kronos Quartet: Black Angels

Kronos Quartet's 1990 recording of George Crumb's harrowing Black Angels remains a peak, to this day, in the long-standing ensemble's catalog of more than 40 releases. They revisit the 20-minute meditation on good and evil—with string players doubling on glass and percussion—in as apt an environment as you could ask for: the hulking battleship moored in the Hudson River.
