Petra's voice and music are not comprised by one single genre, and that is exactly what renders her so unique as a singer. Her three octave range allows her to be just as agile in the classical domain as in the world of pop music. Not only is this vocal mastery apparent from her successful CD's, but also in a live concert setting does she impress and stir emotion by virtue of her angelic voice and personality. She released three classical crossover albums which were certified with gold and platinum. Her success was not left unnoticed worldwide. In 2008 she releases an acoustic album with piano virtuoso Jan Vayne and in the year 2011 she releases the album Touched by Streisand, which commemorates the most beautiful Streisand songs. In March 2019 Petra releases her new album Passione, which features only Italian music and tastefully blends elements from rock, pop, and classical music. In December 2021 there's a new single release! "Ave Maria", the beautiful Schubert Classic.
