This is a small (but free) museum housed in the Montreux Casino building, telling the story of Queen, who recorded many of their albums in this studio, which they owned for part of their music career. Visit definitely recommended for Queen or Freddie fans (but not only). Visitors even get to "mix" a couple of songs, which I found quite fun. The experience feels very special and intimate, so if you have an hour while in Montreux, give it a go!
