 Mike Campbell came to prominence as lead guitarist for Tom Petty and the Heartbreakers. Growing up about an hour away from each other in northern Florida, Campbell and Petty share a similar high nasal croon. For the past decade, Campbell has been making Petty-esque music with his own band, the Dirty Knobs, first as a side project and, after the death of Petty in 2017, as his bread and butter.
