An agile journeyman, Stefanik has already left plenty of evidence of his dexterity in a range of neoclassical styles, and with Reactivity he proves quite comfortable pursuing several disparate sonic directions. The least conspicuous of the album's deviations is "Reactivity 8," a troddin' slow-burner of weathered, rootsy dub. More notable are Stefanik's forays into house territory, "Reactivity 2" and "5" incorporating toms, cowbells and a faint soulfulness reminiscent of a sanded-down Theo Parrish.
The most jarring variation, surely, is "Reactivity 7," an acid burst of metallic, rapid fire percussion that's unlike anything else on the record. All this lends a versatility that keeps the album on its feet for the duration of its 62 minutes. In the main, though, Reactivity is held together by a downbeat backbone that should sit well with anyone with a fondness for Chain Reaction fare (take, for example, the opening and closing cuts, or especially "3").
A stately, almost somber album, Reactivity is choice headphones material, and does come equipped with several fine pulls for more energetic and less solitary enjoyment. It's a record that doesn't clamber for attention, and doesn't seem at pains to forge a bold, singular identity for its creator. But these shouldn't be marks against a listen as consistent, as satisfying, or as cohesive as this one.
