The trademark sound of Tegan and Sara is acoustic guitar-driven punk, lyrics soaked in emotional frustration, and all pulled together by two raw, beautiful voices bouncing off each other.

The musical talent of these Canadian twins caught the attention of Neil Young’s manager when they were 19 years old, and since then they have been one of the 21st century’s most successful female duos. With their 7th studio album “Heartthrob”, Tegan and Sara do something surprising: embrace their inner Cyndi Lauper.

This album marks a turning point in the duo’s career. Their lyrics still ring with the voices of confused young adults on the search for lovers: “Here comes the rush before we touch, so come a little closer”; but the obvious is not that they still sing about the same things, but that they have totally transformed their sound from indie rock to pop.

This new sound is very anti-classic Tegan and Sara; they have gone from a homemade rock style to heavily produced, synth-laden tracks.

For some fans, this may have been blasphemous. It’s the very thing the original style seemed to be swimming against: fluffy, happy, pop music. But the reason this album is so successful is because it is so infectious with styles from 80s pop ballad to dance-happy party tracks, yet still has the classic Tegan and Sara flair in how their voices play off each other while declaring their deprivations.

“Heartthrob” caters to the tastes of many, from those looking for a fantastic 80s synthpop revival to long-time fans of Tegan and Sara, but whichever category listeners fall into they will be impressed by how the sisters have channeled their talents into something more grown-up while still staying true to what makes them so unique.
