Chris Cornell, who sadly passed away two years ago in May. Today, Rage Against the Machine guitarist Tom Morello commemorated his former Audioslave bandmate’s birthday on Twitter, where he told a touching story about his kids and their relationship with their band’s music.

“My kids recently discovered Audioslave,” he wrote. “And while rocking out hard to Cochise, my oldest stopped and said, ‘Dad, it’s really sad that Chris Cornell is dead.’ I replied, ‘That is very true, but let’s keep rocking out.’ And we did. Happy Birthday, Chris.”
