Xasterix, thanks for the link.  I love and want that kulintang music!  (though I have 2 CDs of it  

 ).  
The dancing and fingernails are similar to that found all over Indonesia (especially Bali) and even in Cambodia (all to their equivalents of kulintang/gamelan music).
I noticed that most of the sword work and spear work is done standing up. Some I have seen were influenced by penjat silat and thus low to the ground.  
Again, maraming salamat!
