If you follow YouTube musicians’ live recordings, you get a sense of their gear, and even occasionally register changes: new additions, sudden absences, swapped-out arrangements. Heck, even changes to the draperies and a new paint job. Sometimes such evolutions are announced in the form of “first patch” sessions or mini-tutorials of hard-won tips. Less frequently you’re alerted in advance, as is the case with this benediction from Michigan-based musician Orbital Patterns. A new central processing unit for his synthesizer is due imminently, and this video is, apparently, his last set with the current setup. It’s a beautiful, sprawling mix of melodic patterning and peculiar noises, elegiac drones and sonic coarseness, at once cinematic in its breadth, and at others as personal as a closely mic’d hush.
