By some way Philip Glass's most powerful concert work, Plutonian Ode, sets a scathing anti-nuclear poem by Allen Ginsberg. An initially dark tonal palette, rich in horns and lower strings, generates latent energy that bursts out in despairing, idyllic and grotesque developments. When the soprano's declamations ride over it - as here with eloquence and the necessary stamina - they seem to urge the music on... They culminate in the grandeur of the final variations... all the more devastating for their simplicity, especially so in this intense, committed performance.
