Dragonette's international breakthrough served as a self-possessed introduction. “I just came to say hello,” purred lead singer Martina Sorbara on “Hello,” French producer Martin Solveig's effervescent 2010 single. But by the time of that greeting, the Toronto crew had already banked an arsenal of dance-pop hits. Sorbara's chameleon-like vocals explore an emotional spectrum that complements the band's stylistic swerves—she might utter joyful chirps over New Wave fizz, coo dreamily over piano chords, or snarl her way through a hornet's nest of buzzing synths.
