“Panache Love-In’: These Are Powers+ Apes + Knyfe Hytes + Mixel Pixel. A night running the gamut from gloomy to giddy, teaming the hypnotic no-fi ghost-punk of the always exceptional These Are Powers with the generally dorky but ultimately harmless synth-pop of Mixel Pixel. Moderating this battle for your mood ring is Knyfe Hyts, local psych-metal noizer mutants who can ride a riff into the stoned heavens, and the Apes, whose recent viral mp3 “Beat of the Double” is the most transcendent slice of new-wave-masquerading-as-art-punk you’ll hear all year. 8 p.m., $8. Cake Shop, 152 Ludlow St., 212-253-0036. [INFO] CHRISTOPHER WEINGARTEN
Airwaves + Ghost Lion + The Jack Lions + The Nuclears. 7 p.m. R Bar, 218 Bowery.
Band of Horses + Dirty on Purpose. Pool partiers Jelly NYC are behind this lovey-dovey night at the Brooklyn Masonic Temple, featuring beardy crescendo-rockers Band of Horses and Brooklyn’s Dirty on Purpose. BoH are still touring in support of October’s Cease to Begin, but expect to hear fresh stuff from shoegazing DoP, whose just-released Likes Bees EP features a few new drowsy tracks and a cover of Real Life’s ’80s new-romantic jam “Send Me an Angel.” The perfect opportunity to point at someone across the room and mouth “you.” 8 p.m., $20. Masonic Temple, corner of Lafayette and Clinton, Brooklyn. [SOLD OUT] ELIZABETH THOMPSON
Band of Horses at the Bowery Ballroom
‘Bury Me in Brooklyn Valentine’s Party’ Featuring performances by Golden Triangle, Knyfe Hyts, Robot Death Cult and DJs Gasface, Teenrager, and Mike Sniper, 8 p.m. Death By Audio, 49 S 2nd St., Brooklyn.

‘Diamanda’s Valentine’s Day Massacre.’ There’s no need for lonely hearts’ clubs when Diamanda’s in town. For her third consecutive year, the avant-garde vocalist is hosting her ominous (and fun!) alternative to a conventional Valentine’s night. That means wounded-animal howls and operatic shrieks over piano-driven blues—the perfect antidote to sappy puppy love. Last year she performed songs made famous by artists as diverse as Johnny Cash and Edith Piaf, and her voice is still as electrifying as it was nearly three decades ago. 6:30 p.m. [Tix] and 9:30 p.m. [Tix], $20. Knitting Factory Main Space, 74 Leonard St., 212-219-3006. KORY GROW
The Duke Spirit With The Jaguar Club. They opened for U.K. whippersnappers the Kooks in Brooklyn, but fellow Brits the Duke Spirit get their own show tonight. And they deserve it—although 2005’s Cuts Across the Land proved the band had a knack for fuzzy, dirty ol’ garage-rock, the U.K. press was too busy fawning over Maximo Park to take notice. The record didn’t do much better here, either. But DS’s upcoming Neptune should fare differently: This time around they’ve recruited stoner-rock guru Chris Gross to produce, making good use of frontwoman Liela Moss’s smoldering howl with dark, atmospheric blues. 10 p.m., $10. Union Hall, 702 Union Street, Brooklyn, 718-638-4400, unionhallny.com. [TIX] ELIZABETH THOMPSON
Roberta Flack. She’s one of pop and jazz’s most commanding musical intelligences. But the real reason why keyboardist/vocalist Flack has enraptured audiences for so many decades—solo or in collaborations with legends like the late Donny Hathaway—is a voice that oscillates with emotion like the strings of a fine violin. 8 p.m. & 10:30 p.m., $67 advance, $70 day of show. B.B. King Blues Club & Grill, 237 W 42nd St., 212-997-4144, bbkingblues.com. [TIX] ELENA OUMANO
The Gutter Twins. Composed of Greg Dulli and Mark Lanegan, the Gutter Twins are an alt-rock dream team. With pedigrees that include the Afghan Whigs and the Twlight Singers for Dulli and Screaming Trees and Queens of the Stone Age for Lanegan, their forthcoming Saturnalia captures each artist’s distinct brooding demeanor perfectly. Their songs are dark and profound, and strangely, neither artist overshadows the other. It’s the perfect blend of early-’90s angst and midlife crisis. With Mighty Fine. 8 p.m. Bowery Ballroom, 6 Delancey, 212-533-2111, boweryballroom.com. [SOLD OUT] KORY GROW
Kyp Malone’s Valentine’s Day Dinner. With John Dwyer (ex-Coachwhips, now the Ohsees), Miles Benjamin, and more. 289 Kent Ave (between south 1st and south 2nd), Williamsburg, Brooklyn. [INFO]
Leslie And The Ly’s + The Beatards. If you are feeling really really sorry for yourself today, go to this tonight. I’m serious. Trust me; I will say no more. [Tix]
Matchbox Twenty + Alanis Morissette + Mute Math [Editor’s Note: If you go to this, you deserve to be alone.] M20 started out as a group of dull bar-band rejects, but by 2002’s More Than You Think You Are they’d ended up an appealingly trashy disco-rock crew. Let’s hope the evolution continues on Think You Are‘s belated follow-up, which may or may not be out before Thomas’s next solo disc. Morissette’s either touring in advance of her forthcoming Flavors of Entanglement or in support of her YouTube “My Humps” parody. Mute Math, from New Orleans, sound like U2 rocking a student union. 7 p.m., $49.50-$79.50. Madison Square Garden, 7th Ave. & 32nd St., 212-465-6741, thegarden.com. MIKAEL WOOD
MGMT + Yeasayer. Forecasts call for bloggy skies with a chance of OMG. You’re not getting into this sold-out shows, but in case you can’t wait for Monday’s avalanche of blurry camera phone photos: Brooklyn (we’re told) cloud tasters MGMT made a lofty, catchy, psych-rocky major-label charmer that sounds and feels just like a lofty, catchy, psychy-rocky indie label charmer. The vaguely Afropop-tinged Yeasayer were the hot vaguely Afropop-tinged band until Vampire Weekend stole their sunshine (though Yea’s “2080” trumps anything on the VW album). With Chairlift. 8 p.m., $14-$18, SOLD OUT. Music Hall of Williamsburg, 66 N 6th St., Brooklyn, 718-486-5400. CHRISTOPHER WEINGARTEN
Yeasayer, “2080” (MP3)
Punk Rock Pillow Fight II. For V-Day haters (or the angry in general), take out those frustrations by bopping someone upside the head at Silent Barn’s Punk Rock Pillow Fight II. Sixteen ladies and gents will battle it out for his-and-hers handcrafted championship belts. And don’t forget the rules: 1) Wear a costume (or one will be provided); 2) No head-butting, biting, punching, kicking, or shoving; 3) No “loading up” pillows with rocks or spikes or any other injury-causing material; and 4) You’re out if you fall off or if both knees hit the mattress. Other events in tonight’s massacre include the “Swingers Party” where couples can duke it out with other couples, as well the “Blindfolded Iron Man Match!” Goosedown, anyone? At 7, 915 Wyckoff Avenue, Brooklyn, myspace.com/thesilentbarn, $10 EUDIE PAK

Rufus Wainwright + Sean Lennon. After a spell spent supporting his Rufus-as-Judy double-disc concert set, Wainwright’s back to playing stuff from his own formidable songbook with the help of his own formidable live band. Last year’s Release the Stars elicited more shrugs than it should’ve; pray he plays “Between My Legs” whose droll rock-group vibe ought to survive tonight. Opener (and fellow pop scion) Lennon has released two solo albums in 10 years; both were worth the wait. 8 p.m., $39.50-$55.50. Radio City Music Hall, 1260 6th Ave., 212-247.4777, radiocity.com.
