License No. 1: A Century-Old Bar Learns to Play Live
Boulder's best after-dark music room requires you to go down. Beneath the 1909 Hotel Boulderado, past the lobby's stained-glass ceiling and down a staircase, sits License No. 1 — a low-slung, brick-walled speakeasy with a name that is also a boast. When Prohibition finally lifted in Colorado, one of the very first legal hard-liquor licenses issued to a restaurant went to the bar in this basement. It has been trading on that number ever since.
The history is not decoration. Boulder went dry in 1907, two years before the Boulderado even opened, so the hotel spent its first quarter-century as a grand building serving nothing stronger than a wink. When repeal came in 1967, the basement bar — then known as the Catacombs — grabbed its license and never let go. In 2014 it was rechristened License No. 1, keeping the original permit and leaning fully into the speakeasy bit: dim, subterranean, a little conspiratorial, the walls thick with post-Prohibition memorabilia.
What's new is the noise. The Catacombs was always a drinking room first; License No. 1 has turned it into a genuine live-entertainment calendar. The George Nelson Band now holds down Wednesdays, DJs take Fridays, and live acts play Saturdays starting at 9 p.m. Thursdays belong to comedy — the Underground Comedy Showcase, a reservations-only room with limited seats and a small cover. For a basement bar that could easily coast on cocktails and history, that's a real weekly commitment to putting people on a stage.
The appeal is the opposite of the Fox or the Boulder Theater, and that's the point. You are not here for a 600-cap crowd and a touring headliner. You are here for a small, dark, historically loaded room where the band is fifteen feet away and the whole experience is scaled to a conversation. In a town whose central music problem has been the disappearance of intimate mid-size rooms, a century-old basement quietly booking four nights a week of music and comedy is exactly the kind of small win that adds up.
It also fits the season. Boulder in August is a between-tours town — the students trickling back, the big rooms still mostly dark before the fall calendar kicks in. A place like License No. 1, where the draw is atmosphere and a house band rather than a marquee name, is precisely where a quiet Wednesday finds its legs. You don't check who's playing so much as go and trust the room.
There's a nice symmetry to it, too. The Boulderado's basement earned its number by being first in line the moment the law allowed a proper drink. Ninety years later it's first in line again — this time to prove that a historic bar can be a working music venue, not just a place to admire the woodwork. Find the staircase. Go down. The best-kept room in downtown Boulder has a band in it.
