Regretfully, they have not all been recorded. Wolfl was a strange one as i get the impression his concertos seem to look back to Mozart whilst he is capable of more Beethovian oomph with his solo works.
The 1st concerto is probably the best and the Mozartian theme intro gives us a clue of what is to come. I have played through all the pc's and some of the sonatas and puzzle over his neglect. The Ne Plus Ultra Sonata is a bastard.
