The NEC's Callithumpian Consort takes on Stockhausen today and not by half measures. The piece is From the Seven Days (1968), a collection of 15 text compositions that provide performers with little more than cryptic suggestions. The performance is, by nature, improvisational, and Stockhausen characterized the piece as "intuitive music," to be played without intellect. The Callithumpian Consort takes the stage at 3 p.m., but the perfomrance will last well into the night. The audience is invited to come and go as it pleases. We can't help but imagine the scramble of musicians to call "Not It" on the piece that requires you to "live completely alone for four days without food in complete silence, without much movement." Brown Hall, New England Conservatory, 33 Gainsborough St., 3 p.m. Free.

Movies

With a handful of films under her belt, So Yong Kim already has an impressive reputation in the independent film world. An American who immigrated at a young age from Korea, Kim's films treat cultural displacement and assimilation in original, non-formulaic intricacy. Her first feature In Between Days (2006) is an ambiguous coming-of-age romance shot on hand-held digital video. Kim will be on hand to discuss the film. Harvard Film Archive, Carpenter Center, 24 Quincy St., 7 p.m. $10.

Paleness, Chanteurs

Bostonist may not be down with his weird Hitler obsession, but we have to admit that Antony Hegarty has an amazing voice. Antony and the Johnsons make music that touches all the keystones of a century of melodrama: cabaret, goth, Leonard Cohen, and Current 93. Berklee Performance Center, 136 Mass. Ave., 7:30 p.m. $35.

Racism, Remixed

Paul D. Miller, known by some as DJ Spooky, remixed D.W. Griffith's Birth of a Nation, the 1915 Ku Klux Klan recruiting reel, to demonstrate continuities in American racism that remain even today. Score by the Kronos Quartet. The Beehive, 541 Tremont St., South End, 7 p.m. Free.
