I notice that there are not big pop concerts like in Abu Dhabi or Dubai.
Modern famous pop artist wouldn't come here, I don't know if this has to do with their gage or no interest to organize it.
Classic music is often performed and there are more musicals than in the past, the last one was ABBA.
A famous annual event was the Distant heat festival in Wadi Rum with world famous DJ's but due the complains of the people who live there (and maybe also because of the heat) they canceled this event.
Another famous event is the 10 days Jerash festival where dancers, musicians, performers, singers from all over the world performing in the ancient city of Jerash.
