Tegan and Sara, the Calgary-raised twins who have been darlings of Canada’s indie scene since they were teenagers, are now 32 and thinking about commercial success.

And success is thinking about them. Their live CD/DVD combination package titled Get Along, released last November, has them nominated for best long form video at the Grammys, new territory for the singing sisters.

Tegan and Sara Quin say they’ve changed over the years — they fight with one another less and agree on more.

And when their new album Heartthrob is released Tuesday, fans will hear a new pop sound, polished by producer Greg Kurstin.

Some believe it will be the album that takes them to superstar status.

Tegan Quin says their songwriting is just as introspective as it ever was, and they still consider themselves part of the indie scene, reaching out to the same set of fans.

In this chat with CBC’s Deana Sumanac, they acknowledge that a lot has changed for them and they are growing in a new direction.
