Marius Hubertus Hans Müller-Westernhagen (born 6 December 1948) is a German musician and actor.

[1] Müller-Westernhagen is known for his energetic public concerts, and his fans know his anthem-like songs by heart.

Though written a few years earlier, his song "Freiheit" ("Freedom"[2]) is widely considered as an anthem of the German Reunification.

While keeping away from the merely fashionable, Müller-Westernhagen has nevertheless managed to reinvent himself every few years, and is popular with multiple generations of Germans.

As a result of his singing which almost exclusively in German language in a country where pop and rock are primarily performed in English, Westernhagen originally seemed destined for obscurity, but has managed to use this to his advantage, defining himself as a durable alternative to the perceivably manufactured English-language hits of the US and UK.
