She met
Michael Henry "Mike" Sardina in 1987 when she auditioned for his band. A romance later began and they decided to start a band together titled
Lightning and Thunder, with herself taking the nickname of "Thunder". The pair performed in the Milwaukee and Chicago area throughout the 1980s and 1990s, often at state fairs, including the
Wisconsin State Fair, music festivals like
Summerfest, or as an opening act for major bands (including
Pearl Jam), touring through the area. The band ended in 2006 after the death of Mike due to a head injury. Claire continues to perform as a solo act named
Thunder After Lightning. In 2026, she was a special guest performer on the So Good! Neil Diamond Experience starring Robert Neary Tour, performing at the tour stops in Phoenix, Arizona and in Milwaukee. In 2025, the
Wisconsin Area Music Industry Association (WAMI) awarded the band with a lifetime achievement award in recognition of "giving Wisconsin decades of music, heart, and inspiration". ==Discography==
