I haven't heard it before but if I had to guess, I'd say it is very similar to what a European power metal band would play.
So maybe it is similar with a solo from Helloween, Edguy, Avantasia etc
Yes it does sound like it is pure power metal but I am pretty sure the melody is taken from somewhere, because I've seen them do this in the past.
For example
Here the solo is "Lambada", although it sounds like pure power metal.
Or check this song:
This is written in the Stratovarius style but the instrumental part is made of some famous melodies, but it sounds like it is power metal.
