Note the name Waxahatchee, because Katie Crutchfield's indiepop project deserves to be huge.

Cerulean Salt becomes the band's first album to receive a UK release next month and, on the evidence, deserves to be the soundtrack to every summer night not spent inside a sticky city centre venue.

New single Coast to Coast has a clean-living, summery pop vibe that's reminiscent of the much less clean-living Best Coast, while Lively (sample lyric: "I had a dream last night we had hit separate bottoms") is far darker than the melody lets on. Crutchfield isn't the showiest frontwoman, but whether it's the semi-acoustic Blue Pt II or a full-band cover of Dylan's Knocking on Heaven's Door, her husky voice holds its own.

Sara Quin, one half of the titular Canadian twins, is certainly a fan, but from the enthusiastic welcome it's clear there is only one – well, two – names on everybody's lips. The pair's high-energy set draws heavily from the synth-pop delights of this year's Heartthrob album. When backed with the urgency of their live band, new songs such as I'm Not Your Hero and new single I Was a Fool, with the sort of 80s power ballad piano intro Belinda Carlisle would have killed for, have never sounded better.

Tegan's clear voice is pitch-perfect on her leading parts – startlingly so for a live show – but it's Sara's more ragged delivery that stands out: her gutwrenching How Come You Don't Want Me is the night's most memorable performance. There are old favourites too, including Walking With a Ghost and its dirty White Stripes-style bass, a singalong Where Does the Good Go and the fuzzbox punk of Hop a Plane.
