The Beastie Boys’ Ad-Rock and Mike D sat in on the final day of (Professor?) Questlove’s class on classic albums at NYU. The Roots’ drummer extraordinaire posted photos of the guest teachers on his Instagram today.

As previously reported, Questlove has been teaching a course on “Classic Albums” at NYU’s Tisch School this semester. The class explored the music, lyrics, production and marketing behind certain albums in order to examine why some are considered “classic” or “seminal.”

In related news, Questlove took the stage with Soulive, John Medeski and Bill Evans last night during the sixth installment of this year’s Bowlive at the Brooklyn Bowl.
