Technically, Tulagi is not a punk club. About half the time, the smallish space -- which celebrated its 25th anniversary last year -- is booked by the staff that operates the Fox Theatre next door. But a couple nights a week, the calendar belongs to indie promoter Mike Barsch, who draws on his years of running Denver punk staple the Raven to enlist an impressive revolving roster of up-and-coming indie-rock and punk artists. Death Cab for Cutie, Mars Volta, the Icarus Line and the Alkaline Trio are among the underworld heavyweights who've come to town at Barsch's invitation, much to the delight of the all-ages crowds who regularly pack the place. Local punk bands get their fair share of stage time as well; as the operator of Soda Jerk Records, Barsch has long been a supporter of area acts. In some circles, he's the reigning king of the hill.
