When David Bowie died two years ago at the age of 69, he left a massive void in the music world. But the Celebrating David Bowie tour is helping keep his music alive with musicians who toured with him over the years, like pianist Mike Garson, guitarists Earl Slick and Gerry Leonard, bassist Carmine Rojas and vocalist Bernard Fowler. Well-known guest singers are dropping in at various stops on the tour, which combs through different eras of Bowie’s career. Slick promises that the singers aren’t doing what he calls “Bowieoke” or trying to sound like Bowie. “The singers are interpreting the songs the way they sing them,” Slick says. “The last thing you want to do is try to emulate David, because it’s not possible.” Go to westword.com/music for more of our interview with Slick.
