3.Relief Next to Me

3/10

In their interview with SPIN contributor Josh Eells, the sisters talked about their bond. "Tegan and I," Sara says, "were meant to be, scientifically, one thing. We accidentally split, and there's an incompleteness that comes with that. I feel like I'm walking around with a little bit less than what I was supposed to be given."

4.I Know You Feel It Too

4/10

Tegan also talked about their bond, and why they've chosen to have a career together. "I think we chose to come back together," Tegan says. "Whether this is our first life or our hundredth, our souls chose to do this together."

5.Hell

5/10

While these neighborly streets in L.A. offered ample space for bike riding, the neighborhood that inspired "Hell," the lead single off Sainthood, the duo's new album, is far from idyllic. Vancouver's Gastown was once referred to by a local paper as "Vancouver's Four Blocks of Hell." Tegan used to live there, and Sara maintains a place there so she can be near Tegan and her bandmates.

6.Fix You Up

The sisters get styled for their SPIN shoot.

7.You Wouldn't Like Me

7/10

While the sisters' onstage banter is disarming and funny, sometimes things can get heated, like after one show last year in Scotland where an argument escalated and Sara actually clocked Tegan. "It's not like she's some defenseless kitten," Sara says. "She hit me back three times."

8.Are You Ten Years Ago

8/10

The twins' mom, Sonia, spoke to SPIN about the girls' childhood. "They were enthralled by the sound of their own voices," she says. The only problem was, there was only one tape recorder. Naturally, they started fighting over it. "That," says Sonia, "was the beginning of their music career."

9.Back In Your Head

9/10

Great final thoughts from Sara about her relationship with Tegan: "We were conceived in the same womb, and we look the same, and we've formed this band together -- we have this intrinsic connection. And I will unconditionally love her, and hate her, until the end of time."
