How concerts work is the artist would need to be brought in by an event organiser who in turns has a sponsor willing to pay for that artists. For example, if Mika's price to be playing in country is USD1million, the event organiser has to find a brand willing to pay that amount.That's how it works in Asia. Should the same in most.
So maybe you need to get the attention of radio station to play his new album more. Unfortunately NPIH isn't a "commercial" album, no promos besides in the few EU countries that Heaven Tour went.
GOOD LUCK!!
