Work: Armide

When a conductor decides to lead a performance without a score, it really means two things. One is obvious: a deep and intimate familiarity with the music. Less obvious, though, is the implication of trust in the musicians of the ensemble. On Friday, young Spanish conductor Pablo Heras-Casado delivered a spectacular interpretation of Mendelssohn’s Symphony no.

The second in the Proms Saturday Matinee series featured French Baroque music from the period of Louis XIV, performed by Les 24 Violons du Roy and conducted by Roger Norrington. Interestingly, there was some common ground with the Concert Spirituel concert I reviewed earlier in the Proms season in that they were both projects attempting to recreate 18th-century orchestras.
