Then an Evergreen State College student, Phil Elverum of The Microphones recorded his first album, "Tests", after being given the keys to the studio. Elverum became a fixture of the Dub Narcotic control room. Among albums recorded by Elverum at the studio were the Jon Spencer Blues Explosion. The debut record by Arrington de Dionyso, an Evergreen student with an internship at K, was recorded and released on K as Old Time Relijun. Elverum also recorded Mirah Tov Zeitlyn, known as Mirah, at the studio. These acts helped define a new era of the K Records sound, which shifted its emphasis and started producing records known for their experimental production techniques while maintaining their lo-fi authenticity.
