I have been unable to find any reliable sources covering this work significantly and in direct detail. The PROD-tag was declined because the composer's autobiography was called Hallelujah Junction. Fascinating. But it's still not significant coverage. ╟─ Treasury Tag► Captain-Regent─╢ 07:44, 22 September 2011 (UTC) reply
The piece has been recorded a number of times, inluding by notable performers.
The piece is cited numerous times in musical journals and books; the journal articles all seem to be (subscription required).
The requirements of Wikipedia:Notability (music) are at odds with practice in Wikipedia and other encyclopedias: every composition by classical notable composers deserves an article – that's what distinguishes an encyclopedia from John Adams for Dummies. Very few of the works in Category:Minimalistic compositions will ever appear in the popular press. -- Michael Bednarek ( talk) 13:20, 22 September 2011 (UTC) reply
