[5] Pitchfork Media and Allmusic journalist Mark Richardson defined it thus:[18] The vanishing-point music created by drone elders Phill Niblock and, especially, La Monte Young is what happens when a fixation on held tones reaches a tipping point.
Timbre is reduced to either a single clear instrument or a sine wave, silence disappears completely, and the base-level interaction between small clusters of "pure" tone becomes the music's content.
Operating from the world of lofts and galleries in New York in the mid-sixties to the mid-seventies in particular, and tied to the aesthetics of Fluxus and the post-John Cage-continuum, the group gave performances on the East Coast of the United States as well as in Western Europe.
These performances comprised long periods of sensory inundation with combinations of harmonic relationships, which moved slowly from one to the next by means of "laws" laid out by Young regarding "allowable" sequences and simultaneities, perhaps in imitation of Hindustani classical music which he, Zazeela and the others either studied or at least admired.
[26] During this period, Theatre of Eternal Music member John Cale extended drone techniques to his next band, the Velvet Underground (along with songwriter Lou Reed).
[32][33] Tony Conrad, of the Theatre of Eternal Music, notably made a collaborative LP with Faust which included nothing but two sides of complex violin drones accompanied by a single note on bass guitar and some percussion.
[35] In 1990, British band Spacemen 3 recorded a live 45-minute drone album entitled Dreamweapon: An Evening of Contemporary Sitar Music, with liner notes by La Monte Young.
[39] Across North America and Europe, some musicians sought to reconcile Asian classicalism, austere minimalism and folk music's consonant aspects in the service of spirituality.
