One of the largest free concert series in the country is coming to downtown Indianapolis the first weekend of April, and the lineup is the strongest it's been in years.
Capital One JamFest, the official music festival of the NCAA Men's Final Four, returns to American Legion Mall on April 3-5 with Post Malone, Twenty One Pilots, and Zac Brown Band headlining three consecutive nights. General admission is free for all three days. No catch, no lottery, no secret presale. Just show up.
With the Final Four at Lucas Oil Stadium just a 15-minute walk away, downtown Indianapolis is about to have one of its biggest weekends of the decade. An estimated 140,000-plus fans are expected to attend the music festival alone, and the total economic impact of Final Four weekend is projected at $400 million.
Here's everything you need to know to plan your weekend.

The Full Artist Lineup
The headliners get the billing, but the supporting acts round out what's shaping up to be a legitimate three-day festival.
Friday, April 3: Twenty One Pilots, keshi, Joey Valence & Brae
Saturday, April 4: Zac Brown Band, Russell Dickerson, Ravyn Lenae, BRELAND
Sunday, April 5: Post Malone, Megan Moroney, Dominic Fike
That's a spread that covers alt-rock, country, R&B, and pop across three nights. Whether you're coming for the basketball or the music, there's something worth showing up for every evening.
What's Happening at Lucas Oil While You're at the Festival
The music is free. The basketball is historic. Both are happening within a 15-minute walk of each other.
The 2026 Final Four semifinal matchups are set: No. 3 Illinois vs. No. 2 UConn tips at 6:09 PM on Saturday, followed by No. 1 Arizona vs. No. 1 Michigan at 8:49 PM. The national championship game is Monday, April 6 at 8:30 PM. All games air on TBS.
There's a Hoosier storyline worth following, too. UConn's Braylon Mullins, the Greenfield native and 2025 Indiana Mr. Basketball, hit a 35-foot buzzer-beater to knock off No. 1 overall seed Duke in the Elite Eight. Now he's coming home to Indianapolis with a shot at a third national title in four years. Illinois also brings Indiana connections with Tipton's Ben Humrichous and Cathedral's Jake Davis both in the rotation.

New for 2026, the NCAA is adding a late-night event called Madness After Dark on Saturday, April 4 from 10:00 PM to 2:00 AM at the Indiana Roof Ballroom. The Chainsmokers are headlining.
Capital One cardholder registration opened March 25 and general public registration opened March 27. Spots are limited and may already be claimed, so check the official NCAA page before assuming you can still get in.
How to Get There and What to Know Before You Go
Location: American Legion Mall, 431 N Meridian St, downtown Indianapolis. It's a short walk from Georgia Street, the Convention Center, and Lucas Oil Stadium.
Getting there: The IndyGo Red Line is the move. Park further north near 18th Street or south near Fountain Square and take the bus downtown for $1.75. Event parking near American Legion Mall and Lucas Oil Stadium will run $50 or more, and Georgia Street between South Capitol and South Illinois will be closed to cars for the entire weekend as a pedestrian-only fan zone.
Entry tips: AT&T customers get an expedited "AT&T Fast Lane" entry on Friday. Capital One cardholders have a priority entry line and an exclusive lounge on Sunday. If you don't have either, just arrive early. The gates open well before the headliners take the stage, and the best spots go to people who show up for the openers.
What to bring: Dress for April weather in Indianapolis, which could mean anything from 45 degrees and rainy to 70 and sunny. Layers are your friend. Check the official Capital One JamFest page closer to the event for any bag policies or prohibited items.
