EWA IN TORUN (PL) 12/07/15

Ewa performed 3 songs at this event in Torun (PL) on 12/07/15.
Not at all sure what this event was all about but it appears to have a lot of different artists performing a few songs each.
As far as i know Ewa performed Znak, Ewakuacja and Tajna Misja.  There may have been more, i just don't know i'm afraid to say.
Whatever it was it looks to have been a pretty big deal?  From my limited Polish knowledge it may have been celebrating the anniversary of a radio station (that is probably completely wrong).
You'll find the other performances on Youtube.
