Butch Walker is a multifaceted rocker whose skills run from radio-friendly pop to big-attitude hard rock. After gaining a brief taste of major-label success during the 1980s and '90s -- particularly with Marvelous 3, whose single "Freak of the Week" became a modern rock hit in 1999 -- Walker traded his bandmates for a solo career, starting with the 2002 album Left of Self-Centered. During the 2000s, he released albums that kept him high on Billboard's Heatseekers chart while also cultivating a reputation as an in-demand producer by working with high-profile artists like Avril Lavigne, Katy Perry, and P!nk. Walker continued to balance his performing and production work throughout the 2010s and 2020s, racking up collaborations with Carly Rae Jepsen, Weezer, Green Day, and Taylor Swift, while expanding his musical reach on such albums as 2020's politically charged American Love Story and 2023's soft rock tribute Butch Walker As...Glenn.
