Gavin DeGraw burst onto the music scene with his hit single “I Don’t Want to Be”—the theme from the TV series One Tree Hill—which hit No. 1 on Billboard’s Mainstream Top 40 chart in 2004. But he didn’t stop there: Rolling Stone calls the songs on Sweeter, his most recent album, “taut, efficient, and hook-packed, with guitars bolstering the big choruses.” The Sullivan County native will show off those hooks at a close-to-hometown show at Empire City Casino on September 1.
