In an interview with the BBC, composer Jonny Greenwood asserts that classical music events are too formal.

Greenwood, the guitarist-keyboardist for the British rock group Radiohead, believes his classical-music colleagues should take some cues from pop concerts. “It’s a little dispiriting to find how rigidly programs are set,” he told the BBC, ahead of a concert last week with members of the London Contemporary Orchestra. “It’s very peculiar that usually orchestras know exactly what they are going to play two years ahead of time.”

Along with his rock-music work, Greenwood has collaborated with Polish composer Krzysztof Penderecki and has received commissions from classical groups including the Australian Chamber Orchestra. His “Water,” written for the ACO, received its British premiere earlier this month. Outside the rock realm, he’s best known for his scores for films such as “There Will Be Blood” (2007), “We Need to Talk About Kevin” (2011) and “The Master.”

His suite from There Will Be Blood will be performed at the Chicago Symphony Orchestra’s MusicNOW concert Jan. 19 at the Harris Theater for Music and Dance, 205 E. Randolph.
