Pet Lions was a band from Chicago that was comprised of Karl Ostby, Shuhei Yamamoto, Joseph Murphy, and Matt Dahl. They have only released one studio album, “Houses”, as far as I can see but have released a few singles and EPs before they just dropped off the face of the Earth after 2015. I’ve looked for years but cannot find any information on why they no longer create music, but I have found that Karl has a solo career and his most recent release was in 2019. Their song “When I Grow Old” from “Houses” was features in the Ubisoft video game “Watch_Dogs”.
