What did Helene Grimaud perform as her encores?

Helen Griamud speaks at the post-concert Symphony Chat as Maestro Shui Lan  looks on.

After performing one of the most exciting and adrenaline-driven performances of Brahms's First Piano Concerto with the Singapore Symphony Orchestra in recent memory, Helene Grimaud obliged with two encores:

1. Chopin Étude No.1 from Trois Nouvelles Études

2. Rachmaninov Étude-tableau in C major, Op.33 No.2

For the record, the SSO under Shui Lan also performed at the Gala Concert on 12 January 2013 Richard Strauss's Tod und Verklärung (Death and Transfiguration) and the Asian premiere of Christopher Rouse's Third Symphony.
