"It's a remarkable thing to witness the evolution of a rock band, especially when they grow with as much sophistication and creative maturity as Sunflower Bean do on their third album ... Headful of Sugar is yet another transformative pop moment for the group, marked by a more robust alt-rock sound that evokes the planetary bombast of iconic '90s bands like Garbage, but with their own distinctive candy and smoke flavor ... As a singer, [Julia] Cumming has really come into her own, her voice confidently swooning between warm mid-range resonance and spine-tingling falsetto ... With Headful of Sugar, Sunflower Bean turn the pangs of growing up into hypnotic, intoxicating pop".
