Magic happened on the last night of Steve Vai's Inviolate European tour, at Barcelona's Tivoli Theatre last month.
In the kind of serendipitous moment of audience participation that Dave Grohl seems to specialise in, Vai handed his guitar to an audience member during the show-closing Fire Garden Suite IV - Taurus Bulba, and the recipient left his seat to join the band onstage. The young guitarist, Daniel Jiminez, delightedly soloed with no small amount of confidence, at one point even falling to his knees as he shredded.
Vai has now revealed the full story behind the surprise guest appearance, and it's rather lovely.
The guitarist writes: "On the last show of the European Inviolate Tour on my way to the venue in Barcelona, there was an excited cab driver that wanted me to get into his car to take me to the venue
"During the drive, he was very excited to show me a video clip of his son playing For The Love Of God and I was actually pretty impressed with the way this boy played.
"During the concert that night, I saw the boy with his dad sitting in the audience, so I decided to make his day... and he certainly kicked some ass! It was a splendid way to cap off an outstanding tour."
Jiminez posted his own version of events on Instagram, writing [machine translated from the original Spanish], "Yesterday I lived the happiest day of my life. I'm still processing that it was real. Thank you Steve Vai for inviting me to your concert, thank you for giving me the wonderful surprise of going on stage to play with your own guitar.
"When you approached me and you offered me your guitar I was in shock (I don't know if you can see it in the video but I didn't have the strength to continue playing because I started to cry), and above all, thank you very much for giving me the opportunity to let me know you as a person and being able to chat with you about music.
"This day is going to be burned into my memories; you are a great musician and a great person, you are an example for me to follow."
