They do two general performance types. The first one is a freestyle type of performance from 1 to 10 performers. This would usually be done as a welcoming or background performance while people are arriving or having drinks and can be used to escort guests from one location to another.
Second would be a choreographed show by two or more performers. This is either 7 or 12 minutes long where the performance is choreographed to a piece of music and this is definitely not background entertainment - it is a full on show! Very popular, high impact stuff!
They can also do a wedding ceremony (for lack of a better term) using the fire, incorporating the bride and groom into the 'show'.
