This spirited Canadian group boasts a pretty weighty trump card -- how many lesbian identical twins are making punk-pop albums these days? -- but the real draw here is the sisters' effervescent tunes and forthright 20-something confessionals. Tegan and Sara Quin's folky beginnings and openly gay attitude drew early, fair comparisons to Ani DiFranco, but while ideologically the duo share a point of view with indie-rockers like Sleater-Kinney, musically they're more bent on spunky rock spiked with edgy pop hooks -- Avril Lavigne for grad-schoolers or Joan Jett on a Frappucino rush. Like their last disc, the underappreciated If It Was You, So Jealous froths with spirited production from New Pornographers John Collins and David Carswell (alongside the Quins) and irresistible new wave touches, this time heightened by the buzzing keyboards of Matt Sharp (Weezer/Rentals). Thus, punchy heartbreakers like "You Wouldn't Like Me" -- which contains the priceless summation of girlish lack of confidence, "I feel like I wouldn't like me if I met me" -- and "Speak Slow" build to towering highs, boosted by the twins' interlocking harmonies, and would sound happy next to '80s new wave-power-pop like the Go-Go's and the Plimsouls. The Quins reveal their roots as acoustic folkies on the bedroom musings of "Downtown," but mostly Tegan and Sara bang their hollow-body six-strings in service to the jumped-up type of pop nugget that's become their stock-in-trade. These gals play their hands right, and they could find their names as familiar as those of Avril and Alanis. Lydia Vanderloo, Barnes & Noble
