If you want to get a sense of Tom Petty's influence on modern rock music, listen no further than the guitar-and-drums intro on The Strokes' “Last Nite"—it's nearly a carbon copy of “American Girl”'s iconic lead-in. The air-so-thick-you-could-cut-it-with-a-knife vibes of The Del Fuegos' “I Still Want You”? Check the electric piano and Petty's scornful vocals on “Breakdown”. While not every one of these tunes plays like a full-on appropriation of Petty's best moments, his many signatures—majestic, widescreen strummers; a love of country and the blues; sketches of characters on life's open road—are all over them.
