Stars' music has been described as "beautiful, eloquent indie pop", characterized by lush instrumentation, nimble production and mixing, narrative lyrics, and soft but nuanced vocals. The band's style has evolved from an electronic-pop sound as heard on Nightsongs (released on Le Grand Magistery record label) to more rock-based instrumentation on their last two full-length albums, reflecting the permanent additions of singer-guitarist Amy Millan and bassist Evan Cranley on Heart (released on Paper Bag Records), and eventually drummer Pat McGee on Set Yourself on Fire.
