Former Whitesnake guitarist Adrian Vandenberg has canceled his 2026 tour dates due to unexpected health issues. Why Adrian Vandenberg is Canceling His U.S. Tour"Never in my roughly 60-year long career as a touring/ gigging guitar player [have] I had to cancel a show or tour. "Needless to say I’m really, really sorry to have to announce that I’m strongly urged by the medical specialists involved to not do this upcoming USA tour at this point," the guitarist added. He says that the tour dates will be rescheduled and fans can watch the official Vandenberg website for further details. And of course, you know, as we all know, Whitesnake has been around since the '70s, so it it had already proven its timeless worth."
