"A goodly portion of Happiness Is Happening finds Flügel stretching out and trying out new styles-or styles new to his catalog, anyway. The delightful "Friendship Song" borrows the chord changes from Grimes' "Oblivion" and turns it into a Depeche Mode song circa Speak & Spell, and "Wilkie", similarly springy and similarly naïve, strikes up a dialogue with the New Order of Power, Corruption & Lies ... Two songs in particular show what a versatile producer he can be. The opening "Connecting the Ghost" explores a slow-fast "motorik" pulse, its stately, chugging beat a foil for Flügel to indulge in creamy textures and squealing oscillators; the quick-stepping "Occult Levitation" offers little more than a steady patter of lawn-sprinkler hi-hats and rosy sunrise glow. Both, in their way, are genre studies-Krautrock and techno, respectively-but more than that, they're examples of Flügel's unique sensibility, deft touch, and expressive, unmistakable voice".
