While Ziggie's has long been hailed as Denver's oldest blues bar, in recent years it's expanded into other genres, such as rock, R&B and funk. In addition to an acoustic open-mike night on Mondays, an open jam on Tuesdays and a chance to sit in with featured musicians on Wednesdays, Ziggie's also boasts one of the longest-running blues jams in town on Sundays. And that's where the real action is. The Doc Brown Blues Band and the Blues Allstars alternate hosting the blues jams, which bring in a variety of solid musicians playing covers and originals. Keyboard players need not worry about bringing down a keyboard; the bar has one available for the jams, which kick off at 7 p.m.
