Rancho Cucamonga is getting its own two-day music festival this October, and organizers have split the bill right down genre lines: Bush headline Friday night, while country hitmaker Dustin Lynch tops the bill Saturday. The inaugural Faultline Festival is set for October 16-17 at Morongo Field at The Epicenter, bringing a new large-scale concert event to the Inland Empire calendar.

The festival is presented by Greater Ontario California, known as GOCAL, according to the Daily Bulletin. On Friday, the Grammy-nominated Bush will headline alongside Highly Suspect. Saturday shifts to country, with Dustin Lynch headlining a lineup that also includes Mitchell Tenpenny.

Tickets are on sale now through Ticketmaster.com, per the Daily Bulletin, with two-day passes priced between $62 and $168 and single-day tickets ranging from $39 to $105.

Daytime Programming Rounds Out the Ticketed Concerts

Beyond the evening concerts, the festival includes community programming, according to the organization's own event listing. That includes a Family Zone with children's activities, a pet-focused “Pawsitive Connection” area, and a celebration tied to the Rancho Cucamonga Quakes, the minor league baseball team that calls Morongo Field home. Organizers also plan a nighttime drone show over the stadium during the festival weekend.

The venue itself carries some history. Morongo Field opened in April 1993 as a sports complex built for over $20 million, with 6,588 permanent seats, according to background compiled on Wikipedia. The stadium was known as LoanMart Field beginning in 2013. The Daily Bulletin identifies the festival venue as Morongo Field.
