Cast your eyes on the Billboard chart and it seems like summer 2006 will go down in history as the season of the Latin diva, with Nelly Furtado doffing a soft-focus folkie-cutie image by declaring herself "Promiscuous" and Shakira holding on to the promise of, well, that crazy, sexy, but not quite cool chest move she's close to trademarked via "Hips Don't Lie." Rihanna and Christina Aguilera brought up the rear of the Billboard Hot 100 singles chart last week — solo singers all. But with the on-again, off-again slow fade of Destiny's Child, the imminent demise of the explicitly feminist Sleater-Kinney, and the earlier evaporation of the even more didactic le Tigre, one has to wonder, what has happened to all-girl groups?

Was it a gimmick? Did Newsweek and Seventeen leach riot grrrl's genuine grassroots movement of its "authenticity" and power? Was Sarah McLachlan lame? Was Courtney Love insane? Perhaps the answer is on today's pop charts, where the sole "girl group" — if you don't count the manly guest MC appearances — is the frankly faux Pussycat Dolls, a sorry excuse for women's empowerment if there ever was one.

The scarcity of all-female bands — particularly the variety whose women do more than simply lip-synch on video — has perhaps spread to supposedly more progressive spheres. Erase Errata bassist-vocalist Ellie Erickson notes that when the band recently played Chicago's Intonation Music Festival, she was shocked to discover that their all-female trio made up almost half the total number of women performing among about 50 artists. Even at a more down-low, underground gathering like last month’s End Times Festival in Minneapolis, where Bay Area bands dominated, only one all-girl band, T.I.T.S., made the cut, observes the band's guitarist, Kim West. "When we were in Minneapolis there were so many girls who came up to us and were, like, 'This is so awesome! There are no all-girl bands here and it's so rare to see this,’” she recalls.

Girl groups do persist: the news-making, stand-taking, chops-wielding Dixie Chicks among them. But for every Chicks there's a Donnas, now off Atlantic after the Bay Area–bred band's second major-label release stumbled at takeoff. Is Dixie Chicks credibility forthcoming for commercial girl bands like Lillix, the Like, and Kittie? Some might argue that feminism's gains in the ’70s and ’80s — which led to the blossoming of all-female groups from TLC to Babes in Toyland, Vanity 6 to L7, and Fannypack to Bikini Kill — have led to a postfeminist moment in which strongly female-identified artists are ghettoized or otherwise relegated to the zone of erotic fantasy (e.g., Pussycat Dolls). Gone are the days when Rolling Stone touted the "Women of Rock" in their 1997 30th anniversary issue and Lilith Fair brought female singer-songwriters to every cranny of the nation.

"I think that with the demise of Sleater-Kinney and Le Tigre, it's a very sad time for girl groups," e-mails Evelyn McDonnell, Miami Herald pop culture writer and coauthor of Rock She Wrote. "It seems like the end of the ’90s women in rock era, an era that unfortunately left fewer marks than we hoped it would 15 years ago."
