Coloring Eggs is popular around Eastern, but in Egypt it is also popular around Spring Festivals--an ancient Pharaoh practice. So when you are literary the hottest rock band in Egypt and you want to throw a concert, you bring out the eggs.
The concert that's being promoted has been called off due to security concerns, but the video where the band has a jamming session with Thrwat Zap will be around for some time. This is a humor filled clip where the lead from the band talks about the virtues of eggs.
This is what they call creative advertising. It makes people want to share it and with tit the announcement for the event.
