The moment was pure Brenda. Making her U.S. debut at Washington's Zanzibar club in July, South African singer Brenda Fassie sang passionately from the diaphragm for almost three hours straight. As if that wasn't enough strain on her petite body, Fassie determinedly put on a frenetic dance show. Suddenly her breasts popped out of her costume. The audience gasped, but Fassie unabashedly grabbed her bare bosom and thrust it at the crowd. "This," she proclaimed, "is Africa!"

But America, it seems, was not yet ready for that part of Africa. "The promoters asked me not to do that again," she said afterward. Which is too bad, because back home Fassie is known (and loved) for her outrageousness. Ask a South African if he likes her music, and he's likely to reply with some vivid, raucous tale. In the townships, Fassie is nicknamed "Madonna," after the provocative American pop star. Fassie is the protagonist of countless tabloid stories involving drug use, bisexuality and tantrums of diva proportions (one local paper even reprinted—verbatim—an interview with Madonna, replacing her name with Fassie's). Last April, as she accepted a prize at the South African Music Awards, she flashed her legs at the crowd. "Nice, eh?" she asked, as the audience cheered. But when she returned to her table, Fassie abruptly hurled obscenities at a tabloid reporter who was sitting nearby, calling him "a homosexual who sleeps with men to get stories." Later, as a rival performer did a TV interview, she snatched away the microphone. "This is my night!" she insisted.

Fassie has been shocking people all her life. When she was born in 1964, her surprised family was expecting a boy, so Fassie's mother, casting about for a name, borrowed one from U.S. country singer Brenda Lee. By her fifth birthday, Fassie was already earning money by singing for tourists. As a teen, she landed gigs with popular acts and got on the charts with a single, Weekend Special, which received international air play. Fassie's 1980s efforts—bubble-gum pop sung mainly in English—were musically unremarkable. But young South Africans loved the lyrics of songs like Too Late for Mama that reflected the realities of the apartheid era, so Fassie became the princess of local music.

In recent years, with her girly, high-pitched delivery ripened into a strong-woman wail, Fassie has entered a new phase of her career. The kids call her the Queen of Kwaito, a pulsating pop style that exploded out of the townships in the early '90s and that Fassie quickly adopted. Kwaito (slang for "these guys are hot") fuses slowed American house and hip-hop, British garage and Jamaican reggae, held together with laid-back bass lines and percussion from traditional African chants. Like hip-hop, kwaito has become a cultural movement that incorporates lifestyle and fashion. And like hip-hop, it sells. In South Africa, where a platinum album means sales of 50,000 units, kwaito records regularly sell more than 100,000. Fassie's 1998 album, Memeza (Shout), was the first South African recording to go platinum on its first day of release. It has sold more than half a million units, spurred by the single Vuli Ndlela (Accept the Situation), which still remains on the South African music charts. Her latest album, Amadlozi (Ancestors), has sold more than 300,000 units.

Fassie, 36, is doing so well because while such younger kwaito acts as Arthur Mafokate create dance-party standards, her lyrics address more complex themes dealing with African culture and life. In Sum' Bulala (Do Not Kill Him/Her), she asks taxi operators in the provinces to end their violent rivalries. Fassie has also mostly abandoned English and now sings mainly in Xhosa, Zulu and Sotho. With this marriage of tradition and innovation, she and longtime producer Sello "Chicco" Twala (South Africa's Quincy Jones) are creating the best music of her career. Fassie's new approach invites further comparisons to Madonna, who recently reinvigorated her sound with hip electronica. Fassie likes Madonna but doesn't understand the comparison. "Maybe it's because of the way we dress," she says.

Fassie's personal life remains a work in progress. By her own admission, she spent much of the early '90s in a cocaine haze, missing gigs and becoming a promoter's nightmare, until the overdose death of her lesbian lover, Poppy Sihlahla, impelled her to clean up her act. Ridiculously generous with family, friends and even friends of friends, she has been broke many times, and was once arrested for nonpayment of debts. Those experiences have colored Fassie's perception of success. "I'd rather have happiness than money," she says. "People ask for [money]. Sometimes when I don't have it. I make other people's problems my problem because they want me to; they ask me to. So sometimes I wish I didn't have the little money that I do."

The singer tried to commit suicide three times but says she now lives to see her son Bongani, 17, become a successful musician. Fassie claims that her romantic problems boil down to this: "I'm so good and so loving that men don't believe it."

Kwaito surfaced in New York City in July, when Central Park SummerStage, a popular music festival, featured a young, Fugee-like trio called Bongo Maffin, which has been raising its international profile in the last few months. Fassie, who is shopping around for a U.S. distribution deal, badly wants to be the vanguard of any kwaito breakthrough. Exiting John F. Kennedy Airport this summer, she was a pile of giggles, giddy with excitement about playing the U.S. Then she seemed to recall that she was already a superstar. "Brenda Fassie is in the house!" she loudly announced to no one in particular. A few African tourists who happened to be near the gate asked the Queen of Kwaito to pose for photos, and she obliged. Then, suppressing more giggles, Fassie strode out of the airport, ready to make news.
