by Stephen Thomas ErlewineTegan and Sara's third album, So Jealous, is by far their most ambitious and liveliest record, opening up their punk-folk sound with a heavy dose of new wave sensibility and pop hooks. They started moving in this direction on their previous album, but here they dive headfirst into slick, shiny surfaces, insistent synths, clean guitars, and bright, playful melodies that sound sunny even in minor keys. This musical revamp doesn't betray their nervy emotionalism. Instead, it focuses them, giving their music style and flair that focuses them while making the duo more accessible. And So Jealous is indeed the Tegan and Sara album that could play to a wider audience, but the group remains an acquired taste for one reason: their thin, squeaky voices and close harmonies can be grating to the uninitiated. Nevertheless, for those who have acquired that taste, So Jealous is the most satisfying album Tegan and Sara have yet made.
