AgonyOST is an electronic music producer that primarily creates music that is self-described on their Instagram and Bandcamp as ambient and Lo-Fi. AgonyOST has made little information about themselves available. Even their country-of-origin isn't exactly clear, as their Bandcamp and YouTube both have the location set to the "United States," despite often labelling their music as "UK garage." On June 6th, 2023, their work was unexpectedly promoted by the long inactive Sewerslvt on her Instagram, Patreon, Spotify and YouTube.
