A warm blogospheric welcome to Harvey Sachs and his ArtsJournal blog Overflow. Sachs wrote the only book on music in Fascist Italy, appropriately titled Music in Fascist Italy, in the late 1980s, and has a clutch of other important musical titles to his credit. I dreamed of displaying my fine memory by linking to Andrew Patner's interview with Sachs from March 5, 2007, here, but it doesn't seem to be online. But proof that it happened is right here, just scroll down to that date. Music in Fascist Italy is well worth tracking down in your used-book store travels (that's not just me, right?) to figure out how those Respighi tone-poems jibe so well with Mussolinian rhetoric.
And if anyone has written a history of music in Fascist Italy since Sachs's, please let me know. As I wrote while discussing The Rest Is Noise, that period is one that deserves more historical exploration.
