The first bit sounds a bit like it could be a corruption of what is commonly called 'harp-style' and is practiced by great guitarists such as Tommy Emmanuel, Chet Atkins, Lenny Breau etc.
In this technique you use finger-style to pluck artificial harmonics alternatly with 'real' notes.
It could equally be some kind of effect.
The second part sounds like regular tapping to me.
I could be wrong - there's not much to go on on that mp3.
