The even cooler thing is that guitar virtuoso Steve Vai first auditioned
to be Zappa's backing guitarist, and for Vai to get in, he'd have to play
a set of notes that Zappa was playing. When Steve Vai couldn't do it,
Zappa suggested he join Linda Ronstadt.

Watch him play live:

If anyone can outplay Steve Vai, they deserve a pat on the back because
that guy is absolutely ridiculous. Zappa even introduced the Wah-Wah Pedal
to Jimi Hendrix. Vai now plays with Zappa plays Zappa:

Over the top, but still extremely skilled.
