Aporia is a New Age album from Sufjan Stevens and his step-father and record label co-owner, Lowell Brams, brimming with moody, hooky, gauzy synthesizer soundscapes and created collaboratively in the spirit of the New Age composers who sanded off the edges of their synths sawtooth; Aporia is not a mere curio in the Sufjan Stevens catalog – but a fully realized collaborative musical piece.
