First time Van Halen heard Allan HOLDSWORTH, that's what he said...

Which guitarist made you turn your head around while listening to him?

I have to admit I was floored when I first heard Tom MORELLO's solo in "killing in the name". Of course, I didn't know whammy pedals back then, so I thought this guy had total control over his slide and that he tremolo picked it while perfectly in tune... Silly me!

Another one was Ron THAL solo in 'Fistilous feathers' on his debut album. You can hear it there:

You'll get why I went 'huh???'
