James Chance, No Wave and Punk-Funk Pioneer, Dies at 71

James Chance, the singer, saxophonist and composer who melded punk, funk and free jazz into bristling dance music as the leader of the Contortions, died on Tuesday in Manhattan. He was 71.

His brother, David Siegfried, said Mr. Chance had been in declining health for years and succumbed to multiple illnesses at the Terence Cardinal Cooke Health Care Center in East Harlem.

During the late 1970s explosion of punk culture in New York City, the Contortions were at the forefront of a style called no wave — music that set out to be as confrontational and radical in sound and performance as punk’s fashion and attitude were visually.

Contortions songs like “I Can’t Stand Myself” and “Throw Me Away” filled the rhythmic structures of James Brown’s funk with angular, dissonant riffs, to be topped by Mr. Chance’s yelping, blurting, screaming vocals and his trilling, squawking alto saxophone. He was a live wire onstage, with his own twitchy versions of moves adapted from Brown, Mick Jagger and his punk contemporaries.

Although the Contortions often performed in suits and ties, their music and stage presence were proudly abrasive. In the band’s early days, Mr. Chance was so determined to get a reaction from arty, detached spectators that he would jump into the audience and slap or kiss someone. Audience members often fought back.

“I got a big kick out of provoking people, I don’t deny that,” Mr. Chance said in a 2003 interview with Pitchfork.
