Launched by a fizzing account of the overture to the Paris ballet Les petits riens, the programme centres around three magnificent showpiece arias for Aloysia, famed both for her expressive cantabile and her coloratura prowess. Among her specialities were sustained pianissimo high notes; and I can’t imagine they were more delicately floated than they are by Sabine Devieilhe, a lyric coloratura who combines a pure, sweet timbre and dazzling virtuosity…In one of her signature roles, Devieilhe despatches the Queen’s ‘Der Hölle Rache’ with terrific pizzazz, her poise in alt even enabling her to shade the high-wire coloratura at will.

After a period-instrument reading of the Symphony no.1 that received unanimous acclaim from the critics, François-Xavier Roth and Les Siècles return to Mahler. Joined by the luminous voice of Sabine Devieilhe for the famous finale, they offer us their vision of the Fourth Symphony, which in its own way marks the composer’s transition to modernity, and reveal unsuspected colours and instrumental balances. We still have much to learn about the polyphonic transparency possible within Mahler’s big orchestra!

When Leopold of Anhalt-Cöthen died in 1728, his former Kapellmeister had not forgotten the five brilliant years he had spent in the prince’s service. He dedicated to his memory a mourning cantata almost entirely based on the music of two major works of the mid-1720s, the Trauer-Ode and the St. Matthew Passion. Although the score is lost, the wordbook and other sources of information have now made it possible to reconstruct the work. In his first recording for harmonia mundi, Raphaël Pichon invites us on an exciting musical treasure hunt.

Mozart was just 14 years old when he composed Mitridate, re di Ponto for performance in Milan. An opera seria set in ancient times, it boasts a sequence of spectacular arias for its cast of strongly contrasting characters. At the centre of the action is Mitridate himself – the historical Mithridatus, King of Pontus, a ruler of Persian-Greek ancestry who was a formidable opponent of the Roman empire.
