There’s something pretty irresistible about Go Violets, even before you’ve heard a single note of their music. The Brisbane all-girl indie-pop quartet take the kind of infectiously rosy approach to making music and performing that makes you feel like you’re stuck in some perennially perfect version of your teenage self, with nothing but carefree good times and unadulterated high hopes for the future.

Then you hear their tunes, and before you can work out whether the sweet, summer-y harmonies and tales of innocent adolescent longing are cleverly and carefully reconstructed versions of pop masterpieces from times gone by or whether the reference points are entirely coincidental, you find yourself being absorbed into the simple upbeat beauty of it all and thinking that if there’s any justice in the world, this band will be bigger than Robin Thicke’s ego. That’s pretty damn big.

Heart Slice is their debut EP, and in a nutshell, is a six-track, eighteen-minute blast of power-pop and catchy choruses that will charm you into falling under its spell, even if it’s not exactly ground-breaking or particularly technical stuff. “We’ll stick and never will divide,” sings lead vocalist Phoebe Imhoff on opener and best track ‘Teenager’, starting a lyrical run of subjects that include being “mad about you” and “meeting in the park” – get the idea? Various members switch instruments and take turns at lead vocals, as they do when playing live, with drummer Ruby McGregor and guitarist Alice Rezende swapping spots with ease, while bassist Harriette Pilbeam underpins it all with a punchy pop groove.

There are some pretty goofy lyrics here and there, “Hey Josie, this is not the end, or as the Spanish would say ‘fin’,” on slacker-pop second track, ‘Josie’ for example, but they all add to the overriding senses of charm and fun throughout. Buy this EP, and you’ll listen to ‘Teenager’ about fourteen times in a row – I guarantee it.
