I wonder if others have noticed the stellar work of Marnix van den Berg who has uploaded an amazing array of newly typeset scores to IMSLP.
His latest contributions include the two Concertantes by Solère for two clarinets and orchestra.
Of particular interest is the beautiful scoring for the orchestra - the varied accompaniments and technical assurance which is well above the level of other clarinettist-composers of the period, which we can now appreciate in full score.
