Raised in Hong Kong and now based in Berlin, Alexis Chan produces music under the name of Soda Plains. About once a year, he’s released EPs that have earned him critical acclaim, including Rushes on the conceptually driven, Finnish-run Black Ocean in 2014, and Kickbacks on London’s Liminal Sounds, in 2015. His latest offering is the full-length, self-released album In Tongues. Even within Chan’s niche realm of esoteric experimental music, his practice is singular. The Soda Plains sound is often described as “baroque,” marked by a rapid layering of precise, detailed phrases, heavy in harpsichords and strings.
