My examination of Dmitri Shostakovich‘s passacaglias of the 1940s, a conference paper from two years ago, has now been published in Vol. 13 of Shostakovich Studies, edited by Bernd Feuchtner. Included are discussions of the passacaglia movements from the Eighth Symphony, Op. 65, Second Piano Trio, Op. 67, Third String Quartet, Op. 73, and First Violin Concerto, Op. 77. See this link for more information on the volume.
