Interface's seventh studio album is another collection of the greatest struggles of the human condition. Binding together the band's signature synth production and lyrical themes, Zero-Sum Equation provides the ultimate epitaph on its career. The album's title and theme are prevalent in contrasting songs such as the scathing social commentary of "21st Century" and "No Cause For Celebration", the melancholy "Disappearing Girl", and the gentle "Full Circle".
