Madison Beer at Gallagher Square: The Locket Tour, Sunday, June 21, 2026

Overview

Madison Beer brings The Locket Tour to Gallagher Square at Petco Park on Sunday, June 21, 2026 at 7:00 PM — a stripped-down, intimate setting for one of pop music's most compelling rising stars. The two-time Grammy-nominated artist is joined by Thủy and Lulu Simon for what's expected to be one of Gallagher Square's most anticipated bookings of the summer.

It's also a smart pivot for the 26-year-old singer-songwriter, who's stepped out of the YouTube cover era and into platinum-certified pop with complete creative control over her sound.

Why This Show Matters

Madison Beer is one of pop music's most fascinating modern success stories. Discovered by Justin Bieber at age 13 after he tweeted a link to her YouTube cover of Etta James's "At Last," she spent the better part of a decade rebuilding her career on her own terms — eventually re-emerging as a two-time Grammy nominee with platinum singles, a successful debut album (Life Support), critical acclaim for Silence Between Songs, and now Locket — her most personal release yet.

The Locket Tour is structured around her newest material, but she's known for setlists that span her full catalog. Expect:

• "Make You Mine"
• "Selfish"
• "15 Minutes"
• Fan favorites from Locket, Silence Between Songs, and Life Support
• Deep cuts and rearrangements of her earliest work

Her vocal range and emotional delivery are the centerpiece of the show — this is one of those rare modern pop acts where the live performance genuinely elevates the recorded material.

When and Where

Sunday, June 21, 2026 — Doors 6:00 PM, Show 7:00 PM

Location: Gallagher Square at Petco Park — 840 K Street, downtown San Diego, CA 92101

Gallagher Square is the outdoor green-space concert venue adjacent to Petco Park — a more intimate setting than the main ballpark with a grass general admission area, full bars, multiple food vendors, and unobstructed sightlines.

Tickets

General admission only — most ticket holders are on the lawn at Gallagher Square (no assigned seating).

VIP Experience Available — separate package with premium perks (early entry, exclusive areas).

Pricing varies by date and demand. Buy direct through Petco Park to avoid resale markup.

Who Are Thủy and Lulu Simon?

Thủy — Vietnamese-American singer and songwriter known for genre-blending pop with hip-hop and R&B influences. Her independent debut "Girls Like Me Don't Cry" went viral and earned her a major fanbase.

Lulu Simon — Singer-songwriter and daughter of Paul Simon. She's been building a name as a thoughtful indie artist in her own right, with a polished vocal style and emotionally grounded songwriting.

Both openers are worth showing up early for — this isn't a bill that benefits from arriving late.

Getting to Gallagher Square

The smart play, as always for downtown shows, is the MTS Trolley:

• Three Trolley lines serve Petco Park — Green Line, Blue Line, and Orange Line all stop at the 12th & Imperial Station or Gaslamp Quarter Station, both within one block of the ballpark
• Park & Ride lots offer free parking near trolley stations farther from downtown
• Rideshare — designated zones around Petco Park
• Driving: Parking ranges $15–$55 depending on proximity to the ballpark

What to Bring

• Photo ID
• Your ticket (printed or mobile)
• Cash and cards (Petco Park is largely cashless)
• Layers — June evenings in downtown San Diego cool down once the marine layer rolls back in
• No outside food or drinks — Gallagher Square has multiple food vendors and full bars

Good to Know

• All ages welcome
• General admission only — first come, first served for floor positioning, so arrive early if you want close to the stage
• The Gallagher Square setting is one of the most pleasant concert venues in San Diego — open-air, with downtown skyline views and the Petco Park architecture as a backdrop
• Show falls on the same day as Bob Dylan at The Rady Shell and the NASCAR San Diego Cup Series race at Naval Base Coronado — that's three of the biggest events of the year on one Sunday
• Check the Petco Park bag policy before heading down
