Hatzis wrote Phosphorus soon after the death of his wife’s nephew Cameron. Dedicated to Cameron’s memory, this mysterious yet playful work sees two musical characters engage in a virtual conversation with each other. One, a quiet lament-like harmonic sequence for the marimba, the other consisting of samples taken from Cameron’s DJ mix also titled Phosphorus. These two seemingly incongruous forms of musical expression enter a push-and-pull dialogue in Phosphorus, in which the marimbist must navigate a series of metric modulations accompanied by eerie electronic ambience, pulses of synthesized pitches and samples of Cameron’s “phosphorus” chants and electronic hooks.
