9. Tegan and Sara
Even though they’ve been an active band for the better part of 15 years, Tegan and Sara seem to always come back fresher than before with each new release. Their latest project, Heartthrob, has critics calling it their breakout record in terms of commercial success. Over in Canada, the album won the 2014 Juno Award for Pop Album of the Year, and topped the Billboard Rock Album charts in the U.S. We can definitely see this indie sister show taking off in a big way in the near future.
