She also released a number of covers online and opened for Thirty Seconds to Mars at Palais des Festivals de Cannes and for Florent Pagny tour Vieillir Ensemble and in 2014 for five of Lindsey Stirling's concerts in France.

On 18 May 2015, she released the album Fearless recorded in London and New York City which includes the song "Freeze You Out" written by Sia and Chris Braide.
