(On a side note: Schumann's 'Traumerei' made another appearance in this episode, and in the second episode as well, so it appears that this piece is going to be playing a key role the drama. You can find a link to 'Traumerei' in my post on Episode 1's music selections.)

For Episode 3:

16:50 - Brahms: Piano Concerto No. 1 in D minor, First Movement

The section we hear in the concert hall is from the last part of the First Movement, where piano and orchestra are working their way up to the big finish. This link picks up where that part begins. Then, if you're feeling adventurous you can listen to the entire thing: https://youtu.be/arKoBwtmuX0?t=1414
