Not sure if it's a Japanese thing but 2 hours & above is ideal for a concert , duration wise
flumpool performed here again last Sat & their concert was 2 1/2 hours inclusive of triple encore
On the other hand , Selena Gomez performed here for the 1st time in my country last night & her concert was only 75 mins which doesn't include an encore
Past Western acts that performed here were also criticised for going through the motion in their concerts
To me you pay so much to see them , the least they can do is to give it 150% cos when will be the next time they will come back here to perform ?
