Mastodon is an American heavy metal band formed in 2000 in Atlanta, Georgia. Its lineup of Troy Sanders, Brent Hinds, Bill Kelliher and Brann Dailor stayed unchanged for 24 years. Hinds left in March 2025 and died five months later.

The catalogue is the other reason to go. The Mastodon discography lists nine studio albums, two live albums, three compilations, six EPs, 39 singles and 27 music videos. A band with that much material gives a live set a deep pool to draw from, and a fan has time to work through the records before October 14.

The night suits heavy metal fans and listeners who want to hear a long-running band's catalogue played live. It also suits anyone willing to spend an evening with the albums beforehand.

The age rule is strict. Ages 16+ are welcome with valid ID only, with no exceptions for anyone under 16. Guests under 16 will not be let in with a parent or guardian, per the event listing. Anyone planning to bring a teenager should check the age first, and everyone should carry ID.

Doors open at 6PM and the show starts at 7PM, with the event listed from 6:00 PM to 9:00 PM, Denver time. Arriving when doors open leaves room for the bag search described below.

The listing states that all support acts and set times are subject to change without notice. Check the ticket page again closer to the night for any update.

Bags measuring 12" x 6" x 12" or smaller are allowed inside Fillmore Auditorium (Denver), which sits at 1510 Clarkson. Every bag is searched before entry, and bags that are not clear get an additional search, so a clear bag or no bag at all is the faster way through the line.

Tickets are sold through the ticket page, where the current price is shown. Confirm details with the organizer before heading out, and bring valid ID for entry.

Can a teenager under 16 come with me? No. Guests under 16 are not admitted, even with a parent or guardian.

What time should I arrive? Doors open at 6PM, ahead of the 7PM show.

Will the support acts and set times stay the same? The listing says they are subject to change without notice.
