Who: Foals, a buzzy U.K. post-punk act that digs funky African grooves and is more than willing to rock a house party.

Sounds Like: Frontman Yannis Philippakis, drummer Jack Bevan, guitarist Jimmy Smith, bassist Walter Gervers and keyboardist Edwin Congreave spike their propulsive rhythms with lean, sparkling guitar lines and riotous chants that Philippakis says were inspired by Alan Lomax chain-gang recordings. Cuts like "Balloons" and "Cassius" feature funky guitar riffs, horns played by the Brooklyn Afro-beat group Antibalas, and the atmospheric production of TV on the Radio's Dave Sitek, whose studio techniques included running drums through distortion pedals.

WHO Talk about a self-made star: British singer-rapper Estelle spent her childhood "flipping secular music to gospel" with her eight siblings. "We'd take Brandy's 'Best Friend' and make it about God being your best friend," says the twenty-seven-year-old West London native, born Estelle Swaray. Years later, she took a job at a London record shop frequented by stars like Talib Kweli, and started making her own rap albums. But local labels were baffled by her unique style. "That's been the story of my career," Estelle says, sighing. " 'We don't know what to do with you because it's not been done before.' So I just do it myself."

SOUND Estelle started a label, released mix tapes and approached a pre-College Dropout Kanye West cold after spotting him outside Roscoe's House of Chicken 'n Waffles in Los Angeles. Kanye hooked her up with John Legend, and the two R&B singers hit it off at a studio the next day, and later collaborated on The 18th Day, her debut full-length, which got play nearly everywhere but the States. Together, Legend and Estelle also prepped her forthcoming album, Shine, the first release on Legend's Homeschool Records. Kanye, Mark Ronson, Swizz Beatz and Cee-Lo make cameos on the disc, which swings with the boogie funk of "American Boy" and reggae-rooted tracks like "Magnificent."

REMINDS ME OF . . . When Estelle jumps from singing the hook of the Will.i.am-produced soul-hop single, "Wait a Minute (Just a Touch)," into a laid-back but feisty rap, it's nearly impossible not to mouth the words "Lauryn Hill" — even Wyclef Jean says Estelle's an artistic dead ringer for the Fugee. But Legend says his protégé holds her own creatively. "I think because she's West African and West Indian and British, that unique blend comes through in the eclectic nature of the album," he says.

Cementing that point, Estelle reveals, "Freddie Mercury is my dude, and I loved Guns n' Roses, Aerosmith and Duran Duran." And if that sounds like a strange combination of influences to you, she doesn't really mind. "Love me or hate me, who gives a damn?" she says with a laugh. "I'm a real chick."

WHO Liam Finn is such a dynamic performer that a biker gang once forced him to play all night. When the New Zealand singer-songwriter was in his first band at age sixteen, some brawny motorcyclists invited the group back to their clubhouse for an after-party gig. "We were like, 'OK, we're going to stop playing,' and they were like, 'No, you're not!' " Finn recalls. "All of a sudden it was seven in the morning, and they were all off their faces." Luckily, his more recent gigs have been less intimidating: The twenty-four-year-old has toured with Crowded House, his dad Neil Finn's band, over the past year while also recording his gorgeous folk-rock solo album, I'll Be Lightning.

SOUND Recorded with a mixing deck that once belonged to the Who, I'll Be Lightning melds Elliott Smith-style melodies with loosey-goosey execution and the big, airy harmonies of yacht rock. Finn plays every instrument on the album — and during live shows. Triggering loops he creates via pedals, he'll riff on guitar, go nuts on theremin and pummel a drum kit for a one-man-band extravaganza. "The aesthetic is DIY, leaving the woolly edges," he explains.

IN THE NAME OF ... During his decade-long career, Finn has learned a valuable lesson about band names. His first one was Betchadupa. "I got a T-shirt that said 'Betchadupa I'm Polish,'" he says. "I later found out it meant 'Bet your ass I'm Polish.' It wasn't a wise move because we were forever asked what it means." Things have been smoother as plain old Liam Finn, he says. "Plus, it's a lot easier to stay alive when you're only looking after yourself."
