Vincent d'INDY (1851-1931). L.A.S., December 27, 1915, to Marcel Labey; 2 1/2 pages in-8°. He would be "happy to conduct an act of Bérengère [Marcel Labey's opera]; only...there are a lot of 'seulments'... I don't even know if I'll be able to conduct Arthus [by Chausson], Rouché doesn't mean anything as an era. [...] Because a theatrical machine can't be set up in 3 rehearsals like a concert"; a minimum of 16 rehearsals is needed, and you have to find the time: "it's a problem, not insoluble, but at least as arduous as that of the Balkans"...
