Pop music icon Tiffany will headline the inaugural Faultline Music Fest, a free celebration of community and live music taking place Saturday, Nov. 15, 2025, at the Epicenter Sports Complex in Rancho Cucamonga.

The event, presented by Greater Ontario California , will feature a full day of performances, local vendors, and family-friendly activities from 10 a.m. to 9 p.m. Tiffany, who rose to fame in the late 1980s with hits like “I Think We’re Alone Now” and “Could’ve Been,” has sold more than 15 million albums worldwide and remains one of the most successful teen pop stars of her era. She became the youngest female artist to top the Billboard charts with her debut record, and in 2000, Billboard named her album The Color of Silence one of its “Top Ten Best Albums of the Year.”
