Sistic been the ticketing site for concerts until sports hub has been built and now under sportshubtix. I have used the latter for cnblue concert 2014. One disappointment was I need to pay extra to get the physical tickets, what's free is print-at-home tickets. Hence their service already minus points. Secondly I have tried for jay Chou concert as well. They opened the booking early for ocbc card members. I missed it but hope to grab when they opened to public. And luckily they did their part well in not opening all seats at the cheaper categories to the ocbc card members. I managed to get my tickets. But the concert got postponed (latest update). Their booking fee is also charged slightly more expensive.
