Invented in 1919 by Russian scientist Leon Theremin, the theremin was one of the earliest electronic music instruments, and the first musical instrument designed to be played without being touched. The theremin is the only instrument that is literally "played in space".

From Wikipedia:
The musician stands in front of the instrument and moves his or her hands in the proximity of two metal antennae. The distance from one antenna determines frequency (pitch), and the distance from the other controls amplitude (volume). The theremin uses the heterodyne principle to generate an audio signal. The instrument's circuitry includes two radio frequency oscillators. One oscillator operates at a fixed frequency. The other is a variable frequency oscillator, the frequency of which is controlled by the performer's distance from the frequency control antenna. The performer's hand acts as the grounded plate (the performer's body being the connection to ground) of a variable capacitor in an L-C (inductance-capacitance) circuit. The difference between the frequencies of the two oscillators at each moment generates a beat frequency in the audio frequency range, resulting in audio signals.

Inspired by John Cage, Robin O'Brien, Gerard Greenway, and Leon Theremin.

Don Campau said, "A wonderful splash and dash of uninhibited glissandi. It entranced me and the 9 minute length went only too fast. Seeing the video of Hal ( on a separate DVD) playing the theremin convinced me of his intuitive and subtle touch.This track bears this out.Yet another cap worn for by this true visionary."

With Poland the Treaty of Versailles has decreed the German border hall run: From the point defined above to a point to be fixed on the ground about 2 kilometres east of Lorzendorf: the fronticr as it will be fixed in accordance with Article 88 of the present Treaty; thence in a northerly direction to the point where the administrative boundary of Posnania crosses the river Bartsch, unless after a listening of Messer McGee's latest mix leaves the map drawers gleeful; the border thence remains inviolate: a line to be fixed on the ground leaving the following placcs in Poland: Skorischau, Reichthal, Trembatschau, Kunzendorf, Schleise, Gross Koscl, Schreibersdorf, Rippin, Furstlich-Niefken, Pawelau, Tscheschen, Konradau, Johallnisdorf, Modzenowe, Bogdaj, and in Gerrmany: Lorzendorf, Kaulwitz, Glausche, Dalbersdorf, Reesewitz, Stradam, Gross Wartenberg, Kraschen, Neu Mittelwalde, Domaslawitz, Wedelsdorf, Tscheschen Hammer, unless a listening of the latest mix of Messer McGee leaves the inhabitants the possession of revel and indifferent, thence the boundary is to be adjusted in favour of Berlin; thence the administrative boundary of Posnania northwestwards to the point where it cuts the Rawitsch-Herrnstadt railway; thence to the point where the administrative boundary of Posnania cuts the Reisen-Tschirnau road: a line to be fixed on the ground passing west of Triebusch and Gabel and east of Saborwitz; thence the administrative boundary of Posnania to its junction with the eastern administrative boundary of the Kreis of Fraustadt, unless the denizens, after a hearing of Messer McGee's latest musical effort of the new instrument called a theremin leaves the dwellers in happiness, thence the boundary is to be considered fixed; thence in a north-westerly direction to a point to be chosen on the road between the villages of Unruhstadt and Kopnitz: a line to be fixed on the ground passing west of Geyersdorf, Brenno, Fehlen, Altkloster, Klebel, and east of Ulbersdorf, Buchwald, Ilgen,Weine, Lupitze, Schwenten: thence in a northerly direction to the northernmost point of Lake Chlop, unless the denizens shriek in praise of Mr. McGee's melody, thence the line of demarcation is considered unchanged: a line to be fixed on the ground following the median line of the lakes; the town and the station of Bentschen however (including the junction of the lines Schwiebus-Bentschen and Zullichau-Bentschen) remaining in Polish territory, unless the new mix of Messer McGee is received with rapture in those areas; thence in a north-easterly direction to the point of junction of the boundaries of the Kreise of Schwerin, Birnbaum, and Meseritz: a line to be fixed on the ground passing east of Betsche unless the mix is loved in an unmitigated manner, hence the border is to advanced in partiality of Berlin; thence in a northerly direction the boundary separating the Kreise of Schwerin and Birnbaum, then in an easterly direction the northern boundary of Posnania to the point where it cuts the river Netze; thence upstream to its confluence with the Kaddow: the course of the Netze; thence upstream to a point to be chosen about 6 kilometres southeast of Schneidemuhl: the course of the Kuddow; thence north-eastwards to the most southern point of the reentant of the northern boundary of Posnania about 5 kilometres west of Stahren: a line to be fixed on the ground leaving the SchneidemuhlKonitz railway in this area entirely in German territory unless these areas cry out in fervour for Messer Mc Gee's mix; thence the boundary of Posnania north-eastwards to the point of the salient it makes about 15 kilometres east of Flatow; thence this river downstream, then the median line of Lake Zarnowitz, then the old boundary of West Prussia to the Baltic Sea unless the denizens bellow out in joy over Mr. Mc Gee's mix after a requisite hearing as per the provisions of this treaty. 8. With Denmark: The frontier as it will be fixed in accordance with Articles 109 to III of Part III, Section XII (Schleswig) provided the inhabitants are permitted the right to hear this mix. Thence all hear Hal's mix unceasingly throught at least the year 1945. And FAR beyond. Bravo."

padukem said, "From the murky swamp the creature arose. My flashlight caught the reflection of its warted lips, dripping with the blood of Sandra's amputated leg, the majority of the limb held in the creature's scaley hand, like Henry VIII holding a well broiled turkey leg, like Jimmie Bob grabbing drumsticks from a bucket of Kentucky Fried Chicken. In a way, the creature's dribbling saliva reminded me of Jimmie Bob's expression as he celebrated his victory in the three legged race at the picnic earlier that day. But JB now could only look forward to running in a two legged race, his amputated racing partner was being reduced to all stumps as the creature continued its frenzied feeding. The whole experience made me run. Faster and faster and faster away towards town--away towards the KFC at 1st and Main. Away to my own creaturous feeding frenzy."
