a clip from the movie crossroads portraying Ralph Macchio (the karate kid) playing a badass guitar solo.
Info from IMDB.com
"Though the blues guitar sounds aren't truly coming from Ralph Macchio's fingers, the actor is actually playing note for note the music of Steve Vai and Ry Cooder. His fingering, slides and bends are precise until the "main" solo, which incorporates Paganini's 5th Caprice, in which it is obvious he is not fingering the correct location on the guitar, as well with the patterns, this can be seen since he uses mainly the same pattern (scale on the top frets, then another one in the bottom frets) and all the scale portion of it, the scales are shifting and changing sound, but his patterns remain the same."
"Steve Vai played both sides of the guitar duel, while acting as Jack Butler, the devil's guitarist. Ry Cooder recorded the slide parts and produced the soundtrack."
