Machine Head frontman Robb Flynn and bassist Adam Duce recently gave some students a thrill when they stopped by Booker T. Washington High School in Tulsa, Okla., on Feb. 13 and spoke to students in a music class for an hour.

Duce was invited by the school's music teacher, with whom he's friends, at the request of a student -- but the surprise came when Flynn joined him for the visit. That student posted a YouTube video of the entire visit (watch below), as well as the following message:

"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!"
