Mr. Willis Of Ohio are the most popular screamo outfit out of Switzerland in the 2000's. The band existed between 2004 and 2009. Members had been involved in bands such as Sundowner or Ferguson, which you can find here. Marianne of Ape Must Not Kill Ape plays bass. All lyrics are in German which gives it a special touch in my opinion, maybe cause I'm a native German speaker, I don't know.
I like the mix between aggressive and fast screamo parts and slow sung/spoken passages. The lyrics are very political and deal also with personal problems. It's kind of hard to think of similar bands, so the best thing you can do is listen to the song below. Don't sleep on this band (eventhough they broke up already).
