Machine Head's Robb Flynn and Adam Duce visited Booker T. Washington High School in Tulsa, Oklahoma on Monday, February 13 and spoke to a music class for nearly an hour, at the invitation of the teacher. The video above was shot by one of the students present.

The student wrote on YouTube about the video, "They came to visit our school, Booker T. Washington High School, because our guitar teacher knew Adam Duce and I asked him to see if he could get at least Adam Duce to come to hang out. I could never believe that Robb Flynn would drop by with him as well! They played later on that night at the House of Blues on February 13, 2012, and I headbanged and moshed like none before at the concert!"
