Tenor John Mark Ainsley is already recognized as one of the most exciting talents around. I have seen him on the opera stage singing everything from Schubert to Henze, and here in an all-Beethoven programme he shows a masculine intensity that, particularly in Abenstern, proclaim loud ad clear that we have a first-class Florestan in the making.We get Adelaide and An die ferne Geliebte here, among lesser known works, all sung with a total vocal and emotional commitment. A riveting singer.
