This year’s musical entertainment offered something for everyone, from the swinging Jazz Age sounds at the 60th-reunion tent to the thumping electronic dance music at the fifth. Highlights of the weekend included a performance by Kool and the Gang at the 35th-reunion tent, who were joined onstage by jazz guitarist Stanley Jordan ’81. Over at the 45th-reunion tent, ’71 classmates and other reuners packed performances by rock legend Creedence Clearwater Thursday night and — in a repeat performance from five years ago — Mike Love h’71 on Friday, when he performed two hours worth of Beach Boys surf-rock songs with his band. The annual Battle of the Alumni Bands kept the music going behind Blair Arch during the day on Friday. Even the fireworks made music a theme, with tributes to rock icons David Bowie and Prince, who died this year.
