Check out Steve Vai's free hour-long online guitar lesson via livestream. He attempted to set the Guinness World Record on Thursday for the largest online guitar lesson. Though the final numbers and the world record haven't officially been set, Andy Alt of Guitar International estimated at least 7,000 participants joined in online for the lesson from all over the world. Congratulations Steve Vai!
