I would assume it would be prohibitively expensive for a band with DT's drawing power to play a location like Hawaii.
Well, there's got to be a nice venue in Hawaii that can accommodate DT's stage space and fill up to 1,500-2,000 people. Plus, if they plan on doing a tour in Asia or Australia, they can plan a stop in Hawaii do to a show. That stated, Hawaii is not a sizable market for bands to think it's worth the while.
I'm sure there are venues that could accommodate DT, but the issue is whether the financial return would justify the cost of bringing all the gear and all of the crew to a location for a one stop show. If they draw 2,000 fans at an average ticket price of $100, that's a gross of $200,000. How much of that does the band get? Then figure what it costs to fly all of the gear and crew to the island. DT isn't a big enough band or in need of growing its audience such that playing in a somewhat remote location makes sense if it can't be done for a profit.
DT's never played South Carolina?!
Why is that shocking? SC is a worse market than here in NC, and they only played NC for the first time on the Prog Nation tour (2009?), and only regularly since the Astonishing tour.
South Carolina is also sandwiched between two states that each have twice as many people, and each of which has a major metropolitan area.
Do metal bands ever really come to Hawaii? I know Def Leppard did fairly recently, but I can't recall seeing much of any bands touring there.
I wouldn't think it would make a ton of sense unless the artist can fill a 10,000+ seat arena, but I'm just guessing.
