Mortar boards will fly at Boston University’s Agganis Arena Saturday, but from the hands of an unexpected, more musically-inclined group of students. The Berklee College of Music is hosting their 2013 commencement ceremony at the complex, welcoming the likes of Carole King, Willie Nelson and commencement speaker Annie Lennox. The celebration begins at 10 a.m., and for those who can’t travel into the city, Berklee has made a live stream of the ceremony available, allowing far-flung friends and family to follow along with the graduation festivities online.

On Friday night, Berklee held its annual Commencement Concert, where students pay tribute to honorees by performing music associated with their careers. Past honorary doctorate recipients include Steven Tyler, Aretha Franklin, Chaka Khan, David Bowie and Bonnie Raitt.

Carole King is recognized as the most successful female songwriter in pop music history, while Willie Nelson’s six-decade, 200-plus album career has helped him win dozens of awards. Annie Lennox will be the one addressing more than 900 Berklee graduates at the commencement ceremony, however, and her accolades range from winning four Grammy Awards to the Nobel Peace Laureates Woman of Peace Award.

Prior to last night’s concert, Lennox told the Boston Globe how excited she was to be performing with the students, saying, “It’s a really big production, which is just lovely.” She described the students as playing “exquisitely” in rehearsal, and was humbled to be receiving an honorary degree alongside Nelson and King. “It’s hard to be objective and put myself in the same category,” Lennox said.

The college has been building the buzz and sharing photos of the ceremonies on its Berklee Live page. Students have been tweeting with the hashtag #berkleegrad2013 to capture the memories via social media. Below are some of the snapshots they have taken thus far.
