For a pixie-ish twin-sister act like Tegan and Sara, the inherent novelty and cuteness of your situation can be both a good and a bad thing. It's good because two physically identical 20-something siblings writing songs and strumming guitars in perfect unison is an automatic marketing hook. It's good because you know your musical partner down to her DNA. It's bad, however, because jaded indie snobs will scoff before they've even heard the album.
From the moment Tegan and Sara emerged from Calgary, Alberta, in 2000, they've done everything necessary to quiet the critics who tried to brand them less than authentic. The sisters have released six increasingly popular, increasingly complex albums, culminating with this year's Sainthood. They've made every meaningful stop on the festival circuit, including Coachella, Bonnaroo, and Austin City Limits. And all along, they've steadfastly refused to ditch the matching haircuts.
