"So Good" isn't just another new left-field pop jam from Los Angeles collective Fol Chen. It represents a partnership between the crew, Monome, and Machine Project. Together, they created a handheld instrument called the Tetrafol. According to a press release, it's a "tangible electronic sound toy" that uses tetrahedron detect orientation and motion-gestures, allowing for a musician to warp sounds with a bend of the wrist. Only 100 of them will be made so head to Machine Project if you're interested. You can stream "So Good" below and expect to hear more about Fol Chen's upcoming album on Asthmatic Kitty soon.
