Hagen Grohe
(lead & backing vocals, guitar)

Hagen Grohe is a singer, musician, audio engineer and producer and, with more than 25 years of stage experience, he is certainly one of the best rock voices in Germany right now. His enormous vocal range and versatility make him the perfect front man for a tribute show like THE STARS OF ROCK. Because he interprets the greatest voices in rock with an apparent ease, always authentic and true to the original, although never really imitating, but with his own world-class rock voice.
At the beginning of 2009, none other than Joe Perry, lead guitarist and co-songwriter of the most successful American rock band Aerosmith, became aware of him through a video on the Internet, and promptly engaged him as the singer for his solo album, which was released at the end of 2009. As permanent lead singer with "The Joe Perry Project" he accompanied him and the band on several tours across the U.S., Canada and Great Britain, along with other rock giants such as Slash, Mötley Crüe and Bad Company.

Kerstin Bauer
(lead & backing vocals)

The singer Kerstin Bauer is characterized above all by her vocal versatility. She delights her audience equally as a classically trained soprano and as a pop/rock singer. Few singers manage to reach such a first-class level in both vocal disciplines.
Kerstin received her professional vocal training at the Cologne University of Music and Dance and at the Manhattan School of Music in New York City.
She has already taken on a large number of opera roles and was part of the ensemble in A. L. Webber's musical "The Phantom of the Opera", the original German production at the Metronom Theater in Oberhausen. Kerstin is a regular guest as a soloist in various bands and orchestras, such as the "SAP Symphony Orchestra". She is also a permanent member of the classical vocal ensemble "cantus aureus".
In addition to her concert activities, Kerstin also works as a vocal coach for soloists and choirs.
Since 2020, she has also been publishing original music online.
Kerstin is not only an integral part of The Stars of Rock as a background singer in the implementation of the demanding vocal harmony, but also regularly earns thunderous special applause for her solo performances.
