Puffy dresses, ironic bling and a cheeky attitude are all side dishes to Lily Allen’s vocals du jour. The 21-year-old Brit It gal crooned her way through a sold-out Webster Hall set, dazzling the packed house with both her infectiously catchy pop and outspoken wit in between songs. Allen trashed anyone from The Man to fashion editors, and complemented her talk by taking shots of Jagermeister and smoking (snarkily joking about being fined). Sure, Allen played up to her rebellious, bad girl persona–christening herself as a Diet Lady Sovereign perhaps–but despite her antics, the girl can sing. Supported by a brass and rhythm section, Allen’s band perfected her saccharine-induced, summery beats, an appropriate soundtrack for a holiday in the Caribbean or a rowdy night in LDN. The crowd (a fair mix of bridge-and-tunnelers, Brits and pop devotees) went bonkers during “Alfie.” “Everything’s Just Wonderful,” and of course, the mammoth single “Smile.” Aside from just performing her Alright, Still tracks, Allen beefed up the setlist with acoustic covers of Keane’s “Everybody’s Changing” and The Kooks’ “Naïve.” The finale included a cover of her favorite band, ska pioneers The Specials “Blank Expression” –a classic act that definitely influenced the defiant diva’s ska-tinged soundscape. –Andrea D’Alessandro
