Herrmann holds a PhD awarded for his thesis on Antonio Salieri and his German language stage works. His rediscovery of the lost song of joy Per la ricuperata salute di Ofelia K. 477a by Salieri, Mozart and Cornetti in late 2015 brought him world-wide attention. Among others, Herrmann created works for the Leipzig Gewandhaus Orchestra, the Leipzig armonia wind ensemble, the Heidelberg Symphony Orchestra and the Heidelberg Philharmonic Orchestra. Additionally, he received commissions from festivals like the Heidelberg Biennale for Contemporary Music, the SYLTARTFESTIVAL and the concert series for contemporary music kontrapunkte in Speyer. The Theater Heidelberg premiered several of his stage works, among them the chamber opera Unreine Tragödien und aussätzige Dramatiker and his contributions to the project Das neue Wunderhorn conducted by Cornelius Meister. Herrmann's chamber opera on Shakespeare’s Hamlet, commissioned by the Opernhaus Dortmund, was premiered in February 2017 and performed with considerable success.
His compositions are published by Verlag Neue Musik Berlin and by Friedrich Hofmeister Musikverlag Leipzig. In addition to his profession as a composer, Herrmann also performs as a violinist and a conductor. He regularly works together with the pianist Martin Stadtfeld, the bass-baritone Falk Struckmann, the Mannheim Mozart Orchestra and the Heidelberg Symphony Orchestra as well as the Sinfonietta Leipzig. His album Salieri - strictly private was nominated for three Opus Klassik[de] awards in 2020. Since 2009 he has been art director of the classical music festival Walldorfer Musiktage in his hometown of Walldorf.
