Radical road for 30 or more singers with stones - Weeks, James 1978- (Univ. of York Music Press, 2014)
English words. - Preface, performance notes and composer's note in English. - Duration: 20:00-30:00. - "Radical road is an installation for voices, not a concert work. It has no beginning nor end. There should be at least 30 voices but possibly many more; the duration [...] may be lengthened, but it should not be reduced. Singers should be divided into groups of between 4 and 6 people [...]. Each of those groups has complete autonomy in performance, there should be no overall director leading the performance." (pref.)
