I just returned from a short trip to Waikiki, Hawaii. The sun and surf were glorious. I finally got up the courage to actually become a surfer and not just live vicariously through them. Plus the Pro Bowl was in town with a big street party the night before the game.
All around is music in Waikiki. Of course most of it is of the traditional Hawaiian variety. And I love that stuff. I often tune in stations from Hawaii on the net.
Reggae is also very popular in Hawaii. It's one the reasons Cleveland reggae DJ Tommy Fox moved to Honolulu. Well, that and a girl. His show can be heard on WCSB in Cleveland as it airs live Friday nights on Honolulu's KTUH, Iturnally Dread Meets Rudie's Hi-Fi.
There's some good musicians playing traditional Hawaiian music on the islands. That makes sense. There's also some fine reggae talent in the land of mahalo. There is not very much good rock and pop music though.
Don't get me wrong, I love Jack Johnson, Hawaii's biggest breathrough since Don Ho, but the bands and singer/songwriters that work the club scene are not nearly the caliber of Cleveland or many other mainland cities talent. It makes sense. The clubs want to hire music for the tourists. That would be the aforementioned Hawaiian and reggae sounds. There's not much room for rock bands. So the gigs are hard to come by.
Plus, once you're in Hawaii you aren't doing much regional touring. You're pretty much stuck there. That's not such a bad thing, stuck in paradise.
If you're into the surf life, the sun, sea and sand, the laid back vibe and have good chops you may just be able to carve yourself out a modest living. And a nice living it would be.
