Monica Sanz: Rehearsals for the other side!

Monica Sanz performed yesterday at Shoko (Madrid) and MyMonicaSanz  Channel have uploaded a few seconds video where Monica sings “Born this way” by Lady Gaga.
The description says:

Ok everybody! Promoters didn’t let you access to the party, but they can’t avoid me to record everything happened there…or more! So you’re gonna see much more that happened out of the audience but not of my spy camera!
Here you have my Monica Sanz singing a acapella for the first soundcheck in the early morning…It’s not high quality but…it is!
I will show more (not only from yesterday night although I suppose it’s the most wanted for you now) , just give me time…
