Four Windows. Four minds riding through derangement and beyond as clouds gather over the city of London. Four music students working hard to analyze a unique and extraordinary musical composition. From ‘The Night of the Electric Insects’ through the ‘Songs of Bones and Flutes’ to ‘God Music’ and the return trip, George Crumb’s ‘Black Angels’ — noble; wicked; madness; ethereality. Listen and the sky turns yellow and lightning flickers like burning alcohol in the distance.
