How do YOU guys play FTLOG solo?
You're right - it's completely random.
When Steve Vai plays his superblazing solos in the studio (like for his 7th songs), he just takes a general idea or motif, and gives it 120% - the transcribed rhythms are completely improvised.
There's no way Vai wrote those rhythms out beforehand, and it would be a waste to try and nail it note-for-note. I mean, when he plays it live, he's not thinking about the 32nd notes followed by the 16th note sextuplets or blah blah blah. :bash: That would be an incredible frying of the brain!
I read in another post that someone said that when he attempted a Vai song, he sounded like all the other Vai clones he heard - completely unemotional in attempting to nail the technique. The emotion, the expression, the idea... is more important than, say, the 11 notes jammed into 2 beats starting after the 32nd rest in the six hundredth measure.
So my approach is not much different than yours - I simply take the main notes and 'just go for it' - play as fast as possible, picking every note. I played it once for my eighth grade talent show, and a second time at my high school (for an Oscar-style award ceremony), with my approach to the solo, and it worked just fine.
