These five states-of-matter correspond to the five Classical Greek Elements:
Earth, Water, Air, Fire, and Idea ("Quintessence" meaning "fifth" element). Our concerts explore these five Elements.

This paper presents and explores the use of underwater microphones (hydrophones) as an interface to a recently invented instrument known as the hydraulophone. In particular, the hydrophones, with appropriate processing, give rise to an electroacoustically enhanced hyperinstrument in which acoustic feedback plays an important part.
We begin with a case-study of one of our public art installations, a large waterflute, which is a member of a class of water-based instruments that we call ``hydraulophones''. Hydraulophones are like wind instruments but they use matter in its liquid state in place of wind (matter in the gaseous state). ... What we learned from this case-study, was a specific technique that allows computation to be used to make almost any out-of-tune... play in perfect harmony... Our method uses a filterbank...
We describe a series of performances, events, and water-based brainwave concerts beginning with an event we called DECONcert ("decontamination concert"). These events explore the combined role of water waves, brainwaves, and radio waves in the production, regeneration, or experience of sound waves (music and musical performance)....
