The lineup includes Alarm Will Sound, performing its acoustic arrangements of electronic music by Aphex Twin and works by John Adams; the Bang on a Can All-Stars, playing music by clarinetist Don Byron and others; cellist Maya Beiser; saxophonist Anthony Braxton's 100-tuba ensemble; So Percussion; and the Italian chamber-music group Sentieri Selvaggi.

Performances begin at the outdoor Oval Lawn, then move into the WFC's Winter Garden atrium at 2 p.m.

The Bang on a Can Marathon began as a daylong performance of music by young, unclassifiable composers at a SoHo art gallery in March 1987. It has since been heard at the Brooklyn Academy of Music, Symphony Space, Lincoln Center, and other venues.
