can't exactly notice any loop technic in the second video.
seen him two times here in spain.
it was/is one of my favourite players (athough his music doesn't matches me at all). now i prefer matthias eklundh (also from vai's favored nations label) which nowadays plays with jonas hellborg (both swedes) with a challenging band called Art Metal.
hei rick! check this video for crazy eklundh's guitarrism
at minute 3:20 ... loopy as hell :-)
