Close your eyes, and listen. You've entered a cathedral -- cool tile floors, high ceilings, white marble fixtures, wooden balconies, yellow stained glass sometimes you can hear a car or motorcycle buzz by outside. Inside, every sound -- footsteps, coughing, song -- is echoed beautifully, the natural acoustics of the space allowing them to swirl around a bit before disappearing. Such is the setting for the recording of "Debridement," the second album from Rivulets. Rivulets, aka minimalist singer-songwriter Nathan Amundson, laid the groundwork for the recording at the Sacred Heart Music Center in Duluth, MN, with Alan Sparhawk (Low) engineering. After capturing the core of the songs onto tape (acoustic guitar and voice), Rivulets was joined by friends Jessica Bailiff, Jon Derosa (Aarktica), Marc Gartman, Seth Knappen (ex-Darling), Brian John Mitchell (Remora), Aaron Molina (if thousands), and Mimi Parker (Low), each adding their own stylings to complement his songs.
