As the sound burst from her throat Mangon’s finger locked rigidly against the trigger guard. An instant later, before he could think, a shattering blast of sound ripped through his ears, followed by a slightly higher note that appeared to strike a hidden ridge half-way along its path, wavered slightly, then recovered and sped on, like an express train crossing lines.
Mangon listened to her numbly, hands gripping the barrel of the sonovac. The voice exploded in his brain, flooding every nexus of cells with its violence. It was grotesque, an insane parody of a classical soprano. Harmony, purity, cadence had gone. Rough and cracked, it jerked sharply from one high note to a lower, its breath intervals uncontrolled, sudden precipices of gasping silence which plunged through the volcanic torrent, dividing it into a loosely connected sequence of bravura passages.
He barely recognized what she was singing: the Toreador song from Carmen. Why she had picked this he could not imagine. Unable to reach its higher notes she fell back on the swinging rhythm of the refrain, hammering out the rolling phrases with tosses of her head. After a dozen bars her pace slackened, she slipped into an extempore humming, then broke out of this into a final climactic assault.
Appalled, Mangon watched as two or three members of the orchestra stood up and disappeared into the wings. The others had stopped playing, were switching off their instruments and conferring with each other. The audience was obviously restive; Mangon could hear individual voices in the intervals when Madame Gioconda refilled her lungs.
Behind him someone hammered on the door. Startled, Mangon nearly tripped across the sonovac. Then he bent down and wrenched the plug out of its socket. Snapping open the two catches beneath the chassis of the sonovac, he pulled off the canister to reveal the valves, amplifier and generator. He slipped his fingers carefully through the leads and coils, seized them as firmly as he could and ripped them out with a single motion. Tearing his nails, he stripped the printed circuit off the bottom of the chassis and crushed it between his hands.
Satisfied, he dropped the sonovac to the floor, listened for a moment to the caterwauling above, which was now being drowned by the mounting vocal opposition of the audience, then unlatched the door.
Paul Merrill, his bow tie askew, burst in. He gaped blankly at Mangon, at the blood dripping fro m his fingers and the smashed sonovac on the floor.
He seized Mangon by the shoulders, shook him roughly. ‘Mangon, are you crazy? What are you trying to do?’
Mangon attempted to say something, but his voice had died. He pulled himself away from Merrill, pushed past into the corridor.
Merrill shouted after him. ‘Mangon, help me fix this! Where are you going?’ He got down on his knees, started trying to piece the sonovac together.
From the wings Mangon briefly watched the scene on the stage.
Madame Gioconda was still singing, her voice completely inaudible in the uproar from the auditorium. Half the audience were on their feet, shouting towards the stage and apparently remonstrating with the studio officials. All but a few members of the orchestra had left their instruments, these sitting on their desks and watching Madame Gioconda in amazement.
The programme director, Alto and one of the compres stood in front of her, banging on the rail and trying to attract her attention. But Madame Gioconda failed to notice them. Head back, eyes on the brilliant ceiling lights, hands gesturing majestically, she soared along the private causeways of sound that poured unrelentingly from her throat, a great white angel of discord on her homeward flight.
Mangon watched her sadly, then slipped away through the stage-hands pressing around him. As he left the theatre by the stage door a small crowd was gathering by the main entrance. He flicked away the blood from his fingers, then bound his handkerchief round them.
He walked down the side street to where the sound truck was parked, climbed into the cab and sat still for a few minutes looking out at the bright evening lights in the bars and shopfronts.
Opening the dashboard locker, he hunted through it and pulled out an old wrist-pad, clipped it into his sleeve.
In his ears the sounds of Madame Gioconda singing echoed like an insane banshee.
He switched on the sonovac under the dashboard, turned it full on, then started the engine and drove off into the night.
