Funny, Mister Nobody just posted that vid a few weeks ago on GAB. Great vid! Man, killer player, really cool you got to meet him last night. Love the guitar, too!
Igor sounds much like myself. When I say "conservative" I mean that Igor IMO places appropriate mood swings in the correct place/position. I do that same. I will sweep pick occasionally but very briefly just to add a minor crescendo or quick leap.
If you listen to YJM lately, that's all he does is sweep and rant on endlessly for a long period of time and it all sounds like one endless shred fest; if you will.
I really liked YJM back in the Alcatraz days with former Rainbow front man Graham Bonnet on vocals.
