Although they're based in Beijing these days, they haven't forgotten their Mongolian roots and, dressed in traditional costume and playing traditional instruments, their music has an authenticity and energy that is hard to match. Apparently, Hanggai had been against having a support act on the bill. They didn't need one. The audience - with a strong Mongolian contingent - were only here to see them. They were called back to the stage for three separate encores, with some audience members blocking the stage exit at one point and pleading with them to continue.
It was no over reaction - Hanggai were simply an immensely entertaining band. It wasn't the only stage invasion of the night either. Earlier several Mongolian girls had taken to the stage to present the band members with white scarves - a traditional greeting. During a song about drinking (so good that they played it twice), a man got up to offer the lead singer a bottle of Mongolian baijiu (ridiculously strong stuff), which he promptly necked. One of the Mongolian girls who'd been showing off their traditional dance moves during the gig, also got on the mic to accompany the lead singer in one of the encore songs - Ulan Bator - and to lead the crowd in saying "Hanggai we love you" in Mongolian. I imagine everyone meant it as well, Hanggai were outstanding.
