The Houston multi-instrumentalist Matt Kidd, who writes pastoral, deeply felt compositions as Slow Meadow. Despite initially having minor recognition outside Houston — where glacial, melancholic, piano-centered sound experiments aren’t the city’s chief concern — Kidd’s 2015 debut was still eagerly received by critics like Echoes’ John Diliberto, who elevated Slow Meadow on the same storied Public Radio International show that’s featured Brian Eno, Tangerine Dream, John Cage, and other lions of experimental music. The record also garnered him an entrenched and growing following on Spotify and Bandcamp, where Slow Meadow listeners were treated to several two-song “singles” between Kidd’s full-length ruminations — setting the stage for Costero to be greatly anticipated in ambient, modern composition, and experimental music circles.
