Osker
Osker was a punk trio active in the early 2000s in the United States, in Los Angeles, which according to Allmusic was "led by singer/guitarist Devon Williams."[1]
About their debut album Treatment 5, Allmusic gave a positive review of 3/5, writing "Treatment 5, Osker's debut album, is a rather typical release for the Epitaph label -- aggressive punk with unhinged, snotty vocals and lyrics that alternate between goofy humor and angst-filled catharsis."[2]
