Last Sunday, Tegan and Sara celebrated the release of their excellent new album Heartthrob by playing Artist to Watch s Live in Boston at the Brighton Music Hall. Hive streamed it. Tons of you showed up. It was a fantastic time. The sisters Quin even had a few tricks up their sleeves for this special show, including this performance of Heartthrob tune Love They Say. Here, they strip the song down to its bare-bones essentials. Though Tegan & Sara chose a poppy direction for Heartthrob (which is out today via Warner Bros.), this version makes it clear that their new material can exist in many forms. Watch the performance above and check back with Hive later this week for more on-demand clips from their Live in Boston show.Heartthrob is out now via Warner Bros.
