About

303.show is the fastest way to see what's playing tonight in Denver and along the Front Range. One list. No ads, no login, no algorithm deciding what you see.

Where the data comes from

The listings are built from a community-maintained spreadsheet kept up to date by hand by a local live-music obsessive. This site is a labor of love built on top of that labor of love — all credit for the data goes to them.

Data maintained by the community. Spreadsheet credit + link goes here.

How it works

Once a day, an automated job reads the sheet, cleans it up, and rebuilds this site as plain, fast files served from a CDN. There's no database and nothing to sign into. Star a show and it's saved on your device only.

The name

303 is Denver's area code — and the Roland TB-303, the little silver synth that invented acid house. Tap the logo on the homepage if your sound's on.
