I think the QUBE would be better without the bands.Or the band can play until 0:00am, and from 0:00 am till the end, it would be better to have a DJ playing, because most people going out and coming at the QUBE want to dance on DJ music as in a disco club.You can also notice that each the DJ plays,we can see many people dancing but if the band comes back,many of them stop dancing and go to seat.
I have nothing against the band,but if I decide to go out, I prefer to have a DJ playing.
