Vocal Flame is a fiery sound sculpture made using a Ruben's Tube, which is an acoustic device that visualises sound as a standing wave of small flames.

Satz says: "The soundtrack that animates the flickering flames features a histrionic voice-over, exploring the various embodiments of ventriloquized voices in popular culture, particularly the female voice in film. The voiceover conjures narratives of a biblical burning bush, a self-consuming flame alphabet, the moulded vocal training of My Fair Lady and the acousmatic notion of a voice without source."

Devised and scripted by Aura Satz, voiceover performed by vocalist Jennifer Walshe and music composed by founding member of Siouxie And The Banshees Steven Severin.

Vocal Flame was commissioned by RADAR contemporary arts programme, Loughborough University Music Centre, 2012, where it was first shown.
