Fabio Biondi is a violinist that I have also enjoyed following throughout his career, Mark. He never overplays or exaggerates his undoubted virtuosity and his playing is notable for successfully marrying an elegant refinement with a fiery underbelly. It is also good to see him explore music outside of the Italian Baroque in the case of Leclair and, hopefully, one day he will investigate the music of Biber as well. He is a also a gifted conductor of opera and sacred music. Aside from his many successes in the Italian Baroque repertoire, his very unexpected recording of Bellini's I Capuleti e I Montecchi was a total success, in my opinion, as was his recording of Handel's Imeneo.
You should also investigate Jean-Fery Rebel, a contemporary of Leclair. One of my favourite violinists, Amandine Beyer, recorded a superb selection of his violin sonatas. And there is also another fine CD by Ensemble Rebel that covers his trio sonatas.
