I see no public replies to this message, so I'll take a stab. The octave etude is a goldmine of possibilities for pedal effects. Experiment and listen hard, and you can differentiate yourself from the competition. Similarly, try Ravel's Tombeau de Couperin for music that is not heard every day, deceptively simple, but full of expressive possibilities. The opening movement sounds great done "chaste" and Lipatti-like, not drilled out as we sometimes hear. If you need to cover 3 historical periods instead of 4, you can leave out classical and the Ravel will cover for it.
