Butch Walker is a born hitmaker with a rock-star bite. Born in Georgia in 1969, the singer-songwriter has lived many music lives: as a guitarist for glam-metal band SouthGang in the late '80s, frontman for ‘90s power-pop trio Marvelous 3 (who scored an alternative hit with 1999’s “Freak of the Week”), and a freewheeling solo artist by the 2000s. Over a prolific string of records, Walker has churned out riff-heavy rockers and rollicking heartland anthems, crafted a rootsy political “rock opera” with 2020’s American Love Story and even transformed into retro piano crooner “Glenn” for his 10th solo album. The common thread? His knack for delivering a fiery hook every time—a big hint at his other career as a pop producer and songwriter for artists such as Katy Perry, P!nk, Green Day and Taylor Swift.
