The new recording captures the pianists’ special artistic relationship with Philip Glass – a follow-up to the Double Piano Concerto the composer dedicated to the sisters in 2015. They are known for the fusion and energy of their duet, pursuing a stunning career all around the world, supporting both the classical repertoire and the contemporary creation. Philip Glass’s music occupies a special place in Katia & Marielle Labèque’s creation since they are already dedicatees of his Double Concerto for two pianos. It’s the composer himself who chose to adapt his opera Les Enfants Terribles after Jean Cocteau’s novel for them, in a suite for piano duet.

The Mass in E flat was most likely composed for the 1804 Marienfest in Eisenstadt, an annual event celebrated with great pomp and splendor to honor the Fürstin Maria's name day, usually on the weekend following the Mariä Geburt observance (September 8). For the Marienfest, the Fürst usually hosted a banquet, a ball, and a concert, in addition to a military parade and fireworks. He also commissioned a new Mass each year (the late masses of Haydn and the Mass in C of Beethoven owe their existence to the Marienfest).
