2011 release of Hunter x Hunter (Chimera Ants arc):
In the episode where Gon and his friends enter the castle of ants through the hole made by Knov , everything goes like a slow mo and an epic music hits. I apologise for not mentioning the episode number. This music is repeated several times during the arc after the inception.
I have listened to various OST's from Hunter x Hunter but I don't think any of them are the one which I am looking for...
Can someone Identify the music that was playing??
