Born in Hamburg, Ludwig was from grade three a member of the boys' choir Chorknaben Uetersen.[1] He studied voice at the University of the Arts Bremen with Thomas Mohr and Krisztina Laki, with a focus on historically informed performance.[1][2]
In 2012, Ludwig appeared at the Laeiszhalle in Hamburg with the Franz-Schubert-Chor in a program combining Schubert's Mass No. 2 in G major with Dona nobis pacem by Pēteris Vasks and Martín Palmeri's Misa a Buenos Aires (or Misatango).[3] He has performed the tenor part in Bach's St John Passion, both Evangelist and arias, for example at St. Nikolai in 2016, conducted by Volkmar Zehner. A review noted that he used his bright and agile tenor voice for an intense dramatic narration.[4] He appeared in the opening concert of the Elbphilharmonie in Hamburg in 2017 with a vocal quintet called Ensemble Praetorius, founded for the occasion.[1][5] In 2019, he appeared as a soloist with the Balthasar-Neumann-Chor und -Ensemble [de] conducted by Thomas Hengelbrock at the Kölner Philharmonie, performing Schumann's Missa Sacra.[2] He performed the first tenor solo part in Monteverdi's Vespro della Beata Vergine at St. Martin, Idstein, conducted by Franz Fink, alongside soprano Elisabeth Scholl and bass Johannes Hill. A reviewer credited the six soloists with perfect technique and harmony among their voices in the ensembles.[6]
Ludwig is a member of the vocal quartet Quartonal. Founded in 2006, they won first prize at the 2010 Deutscher Chorwettbewerb.[7]
