in 2006 glanert's opera "caligula", on a libretto by hans-ulrich treichel after the play by albert camus on the last days of the roman emperor caligula, was first staged at the oper frankfurt, conducted by markus stenz. a recording of this production was reviewed:it's a scenario that glanert could easily have depicted in sensationalist terms, but the hallmark of his score is its refinement, both in the wonderfully imaginative sound world he creates, and in the smoothly contoured vocal lines. it's an impressive achievement, and the sense of scarcely suppressed menace that pervades the work and carries unmistakable echoes of strauss's elektra and salome is powerfully conjured.
