First by the pillar in front of me, then by the deep passion of the performers. This is not exactly a circus imo, they do a healthy mix of performing art that spoke to the audience in different ways. I had low expectations going to this show thinking it'd be a makeshift act put together by locals to earn a living, but I was so wrong (donated more for my misjudgement). They are team of devoted art students who put together this act based on their individual talents (yes, most of them do more than 1 role). From a deep Angkorian plot (I still don't fully understand the story) to heart stopping aerial flips, it is a must visit if you're in town, cause I just don't know what else you'd do. And go early !
