The Lion's Lair at 2022 East Colfax Avenue is Denver's version of CBGB's — a gritty, legendary dive bar and music venue that's been part of the city's punk, rock, and underground music scene since the 1990s. The space itself dates back to the 1930s, when it was known as The Playboy Club. Today it's one of the last true music dives on Colfax, where bands from all over play sweaty sets to crowds who actually care about the music.
