In-N-Out Burger is holding a “Battle of the Bands” contest as a lead-up to its 75th anniversary festival.

The winner will perform at the event, which will take place Oct. 22 at the In-N-Out Burger Pomona Dragstrip.

The contest will take place online and will be judged by In-N-Out president and owner Lynsi Snyder-Ellingson, and .48 Special, the In-N-Out company band, according to a news release.

There is an entry fee of $75, with proceeds benefitting the Slave 2 Nothing Foundation, an organization set up by Snyder-Ellingson and her husband Sean Ellingson to combat human trafficking and addiction.

The contest’s website began accepting submissions on Monday, June 26. Applications will be accepted through Aug. 4.

Bands must submit videos of live performances that can’t be longer than 6 minutes and can have as many as three songs.

All genres of music are accepted, but bands must have at least three members, including a singer and musicians, and they must be at least 18 years old.

The winner will be announced Sept. 1 and informed via email and phone, according to the website.

The festival will include a benefit concert for Slave 2 Nothing featuring .48 Special and ZZ Top. It is a separate ticket, not included in general admission.

Other entertainment includes drag racing, a car show and carnival rides.

In-N-Out Burger is based in Irvine but was founded in Baldwin Park by Lynsi Snyder-Ellingson’s grandparents in 1948, hence the band name .48 Special.

The chain announced the festival nearly a year in advance, when it became the title sponsor of the dragstrip, which is part of the 487-acre Fairplex, home to the LA County Fair.
