From the musical point of view we are served pretty well here in the UK. I am out in the sticks a bit which means there is not always much happening on the doorstep, but then again I would not want to live in somewhere like London, Manchester or Birmingham.
I spent several years in Dubai, very little in the way of new local bands with original (western) music but a good scene with plenty of visiting artists. One big advantage over the UK was you did not have to book months in advance to get tickets for major artists.
The local music with its unusual scales is not the freindliest on western ears, but I saw a fantastic orchestra combining arabic and western music into something rather wonderful.
There were also some very good cover bands with hotel residences. Yes, some were "Murf and the Magic Tones" but there were also some hard rocking Filipino bands who were well worth watching.
From a non musical standpoint if I had to relocate and money was no object you would find me the German speaking part of Switzerland somewhere near Luzern.
