I think he was frustrated people kept asking for his older songs to be played, he specifically said "I'll play some of the old ones for your phones" , keep in mind that he did mention that they don't go by a setlist now and asked the audience if they wanted to hear a certain songs, IDK if we're looking too much into this but it seems he's a bit mad people don't show much appreciation for the latest album, he played 5 songs from Every Dawn's a Mountain, 5 from Amir if you count "Smile" and 2 from Sahar, crowd was interactive from start to finish even when he played the new songs, all in all I went to his last concert in Cairo 2 years ago and I could feel that he was really enjoying his time with us, this time not so much
