Pop Group (Music Group)

His band, the Pop Group, was anything but pop, blending anti-authoritarian fury with a ferocious mix of punk, funk and experimental jazz.Mark Stewart, the incendiary frontman of the British post-punk band the Pop Group, whose explosive mix of funk, noise rock, free jazz experimentalism and anti-authoritarian rage made a mockery of the group’s sunny name, died on April 21. He was 62.His death was announced in a statement by his London-based recoding label, Mute. It provided no other details.The Pop Group emerged in Bristol, England, in 1977, as punk rock was shaking the foundations of the British music scene. Mr. Stewart found inspiration in punk’s iconoclastic fury. “There is the arrogance of power,” he once said, “and what we got from punk was the power of arrogance.”Onstage, the band created a cyclone force that put many punk bands to shame. Gyrating manically and barking rebellious lyrics through his pouty, Jagger-esque lips, Mr. Stewart whipped audiences into a frenzy with songs like “We Are All Prostitutes,” the band’s best known single, from 1979, which reached No. 8 on the British indie charts. The lyrics include these lines:We are all prostitutesEveryone has their priceEveryoneAnd you too will have to learn to live the lieLive performances by the Pop Group hit with “such indomitable force and such sudden visceral rage that I could barely breathe,” the musician and writer Nick Cave wrote in a tribute on his website, The Red Hand Files, after Mr. Stewart’s death.Righteous fury was as intrinsic to Mr. Stewart’s personality as it was to his music. “Mark taught me many things about life,” Mr. Cave added, including the idea that “sleeping was a bourgeois indulgence, and that the world was one giant corporate conspiracy, and that one way to win an argument was to just never, ever stop shouting.”The band scarcely made a dent commercially, but that made sense, given its contempt for all things capitalist. As Mr. Stewart put it in a 2015 interview with The Arts Desk, a culture site, “The Pop Group were really that Situationist idea of an explosion at the heart of the commodity.”Mr. Stewart performing onstage in 2012 in Leeds, England. After the Pop Group broke up, he remained prolific, collaborating with Trent Reznor of Nine Inch Nails, Tricky and Massive Attack, and releasing a string of eclectic solo albums.Andrew Benge/Redferns, via Getty ImagesMark Stewart was born in Bristol, in South West England, on Aug. 10, 1960, one of two sons of an engineer father and a mother who worked with children with learning disabilities.Bristol in the 1970s was a rough town, Mr. Stewart once said, and his towering stature — he was already 6 feet 6 inches tall as a preteen — made him a tempting potential recruit for local boot-boy gangs. But the thug’s life was not for him; music was his passion — even though he and his friends considered themselves musical misfits, scouring junk shops for obscure jazz and funk records, wearing mohair sweaters inspired by the Sex Pistols and staging punk shows at a local youth center.“The local gangs really, really had it in for me,” he said in the Arts Desk interview. “They wanted me to join their gangs but didn’t realize I was only 12. They thought I was about 20. So they’d smash all the youth club windows. I had to climb out of toilet windows.”Music was a way out. “If there’s not too much going on in the town you’re in, you dream,” he said in 2014 interview with Vice.Mr. Stewart formed the Pop Group in 1976 along with the band’s original members: John Waddington (guitar), Simon Underwood (bass), Gareth Sager (guitar and saxophone) and Bruce Smith (drums).The band’s name came from Mr. Stewart’s mother. “I think she said, ‘Oh, Mark’s forming a pop group,’” he told Vice. And at the outset, he said, “we thought we were.”The band’s first album, “Y,” which was released in 1979 and produced by the British dub master Dennis Bovell, made little commercial impact.“These heavyweight journalists thought we were being deliberately obtuse,” Mr. Stewart told Vice, although NME, the taste-making British music publication, called the debut “a brave failure. Exciting but exasperating.”The Pop Group did anything but mellow on its second album, “For How Much Longer Do We Tolerate Mass Murder?,” released the next year; it crackled with angry denunciations of Thatcher-era England. Though some dismissed it as “self-righteous soapbox agitprop,” the critic Simon Reynolds wrote in “U.K. Post-Punk,” a 2012 collection of his essays, the album, like “Y,” came to be a considered a classic by many.In a look back at the album upon its rerelease in 2016, the site Punknews.org observed: “This is the noise of a collapsing society caught on tape, running through the gamut of paranoia and death. Dig it.”The band broke up not long after the second album’s release, but Mr. Stewart remained prolific, collaborating with Trent Reznor of Nine Inch Nails, Tricky and Massive Attack, and releasing a string of eclectic solo albums over the years that, characteristically, were as subtle as a bazooka.The first, “Learning to Cope With Cowardice,” from 1983, was rereleased in 2006. It inspired the music site Pitchfork to note the single-minded intensity of this “possible madman and authority-critiquing refusenik that was marginalized in his own time, only to later be viewed as a seer.”Little is publicly known about Mr. Stewart’s personal life, and information about his survivors was not available.In 2010, he reunited with the Pop Group and released two more albums, “Citizen Zombie” (2015) and “Honeymoon on Mars” (2016). Both its albums and live performances showed that the band, and Mr. Stewart, had not lost a flicker of their fire.“It was good to be reminded of how singular and beautifully abrasive the Pop Group could be,” Ben Beaumont-Thomas of The Guardian wrote in a review of a 2010 London performance, “and how dreadfully conservative most rock music since sounds in comparison.” More
