Three hundred years since his birth, Gluck is still remembered for a mere handful of arias, yet he was the most powerful operatic reformer of his time. It is amazing to find in Daniel Behle's fine recital previously unrecorded items from Antigono and Semiramide. The style veers from demonstrative old-style serious opera, with lots of decoration, to eloquent, new-style declamation. As a tenor, Daniel Behle naturally offers the French rewrite of Orphée et Eurydice, flowingly done. His voice is clear, shapely and unfussy, bringing an ideal clarity to Gluck's transparent lines that is well matched by the exciting Greek period ensemble Armonia Atenea.
