“I happened to meet Marco Celli Stein on the occasion of an event particularly dear to me, that was the creation of a Chamber Orchestra which bears my name. As artistic director Marco Celli Stein acted with the utmost reliability. As flautist I appreciated his technical virtuosity besides his phrasing and interpretation.”

“I could listen to the Fourth Symphony by Robert Schumann performed by great conductors and as far as the introduction is concerned I don’t remember I ever heard the intuitive meaning of the phrasing in the interpretation of Marco Celli Stein.”

Francesco Siciliani

“This evening performance has been for me a revelation and seeing Celli Stein conducting I could observe a gesture that was totally musical: without beating scholastically the time, but letting it flow in a natural way together with the phrasing. Besides, he succeeds in having performed the right accents avoiding the performance of the wrong ones: he reminds me of Prêtre.”
