For the “Killer Tracks and Curve Balls” episode, her coach Ronan Keating chose the no. 1 song of the century for her–“Somewhere Over the Rainbow.”

Natalie Bassingthwaighte said “You are blossoming into such a great performer. I really believe that you’ll be in the grand finals after that performance.”

Dannii Minogue said “You’re having a very good night young lady. I love that song choice, it’s so beautiful. The only reason I didn’t stand was because the opening note, it faltered. The rest of it was flying and the audience loved it.”

Redfoo said “Marlisa, this performance moved me as your first performance did. Your voice is so pure. I hope Australia reward the performances tonight that moved them.”

Ronan Keating said “You deserved to be in the grand finals, Australia pick up the phones and vote please, you’re amazing!”
