Lisztomania is a 1975 British surreal biographical musical comedy film written and directed by Ken Russell about the 19th-century composer Franz Liszt. The screenplay is derived, in part, from the book Nélida by Marie d'Agoult (1848), about her affair with Liszt." All of these references are interesting, but my favorite new reference is in this fun, interesting video done by Ben Laude with Tonebase. Some speedy fingers here, no doubt!
