I'm sorry to inform you, but we have no metal scene here. ( I assume you will be visiting Oahu). There are no concerts coming at the time you will be here, in fact, the last concert I went to (Testament) was years ago. The current trend here is bands that play cover songs from alternative/nu-metal artists. You will find these kinds of bands in all of our so-called "rock" clubs. We do not have metal stores unless you consider Hot Topic metal...it's more goth/nu-metal. You can try Hawaii's Natural High, but as you can tell by it's name it sells more than just shirts. It's located in Waikiki which is where I assume you will be staying.
One site that you might want to check out is
www.slugrocks.com. Slug is a local band that plays some metal covers. There is a list of clubs you can check out, but I'm pretty sure there won't be any metal band playing. Gussie's is your best hope (located near the airport - we have only one airport). Wave Waikiki caters to the alternative/nu-metal crowd. You can also try Moose's in Waikiki, but be prepared to listen to Papa Roach, Incubus etc. covers...but if you like that stuff then great!
To sum things up we have no metal scene here. That scene died-out long ago in the 90's. All the decent metal bands we did have broke up long ago. Nobody tours here, and rightly so, because they wouldn't make any money. Someone huge like an Ozzy or Metallica could profit, but if Iced Earth came most people here would be like, "Who's Iced Earth?" So there ya go!
Damn, I thought this thread was about Marty's old band!
