A classically trained techno changeling, John Tejada is a highly regarded and prolific electronic producer and DJ, working in styles ranging from IDM and tech-house to downtempo and hip-hop. Since debuting in the mid-'90s, he's racked up an impressive, acclaimed catalog of albums, singles, and DJ mixes, including collaborations with legendary MC Divine Styler. In addition, he's released several albums of downtempo post-rock as one-half of the duo I'm Not a Gun, and collaborated with comedian/beatboxer Reggie Watts as the improvisational house duo Wajatta. Tejada is also highly prolific as a remixer, with clients including the Postal Service ("Such Great Heights"), Telépopmusik, Kevin Saunderson, and many others. His early solo albums included the Detroit techno-esque Little Green Lights and Four Inch Faders (1998) and the laid-back instrumental hip-hop of The Matrix of Us (2000). Numerous mixes and collaborations with Arian Leviste appeared throughout the remainder of the decade, as well as tech-house full-lengths on Plug Research and Tejada's own Palette Recordings. Much of his work since the early 2010s has appeared on German techno institution Kompakt, from the melodic electro-techno of 2011's Parabolas to the dubby minimal techno of 2021's Year of the Living Dead. Further Palette albums such as Resound (2023) and The Watchline (2025) have coincided with Tejada's activity as one-half of Optometry with singer/songwriter March Adstrum.
