Cal Jam, short for California Jam, is a storied rock festival that first roared to life on April 6, 1974, at Ontario Motor Speedway. Co-headlined by Deep Purple and Emerson, Lake & Palmer, the event drew hundreds of thousands and set a new bar for loud, large-scale rock gatherings.
Decades later, Foo Fighters revived the spirit with Cal Jam 17 and Cal Jam 18 at Glen Helen Regional Park in San Bernardino. The weekend fused marathon sets and surprise collaborations with festival comforts like on-site camping, free carnival rides, a water park, and a rock museum, turning the grounds into a rock playground. The 2018 edition stretched into a 12-hour blitz and even delivered a high-voltage reunion by Nirvana members with guest vocalists.

Music festival essentials usually include your ticket or wristband, ID, cash or card, a refillable water bottle, portable phone charger, sunscreen, comfy shoes and a light jacket or poncho in case of weather changes. Be sure to check the festival's rules for what's allowed as every festival has its own policies.
Many festivals host official aftershows featuring artists from the main lineup as well as special guest performers. These events typically take place at nearby clubs, theaters, or venues after the festival grounds close.
Aftershows require separate tickets from the main festival pass. Availability is limited and often sells out quickly, especially for smaller venues or artist headliners. Some events are 18+ or 21+, depending on the venue.
Comfort and weather-ready gear are key. Opt for breathable, layered clothing, comfy shoes for walking and standing, and sun protection like hats or sunglasses.
Most festivals have official merch tents or booths on site where you can purchase artist and festival-branded items like t-shirts, hoodies, hats, posters and more. Merchandise is typically available at a central location of the festival or near main stages.
