As the arrival of spring melts away the remaining sludge of the February doldrums, comedy blooms anew in Denver this March. With visits from veteran standups, hilarious newcomers, and a chance to see the stars of two of TV’s funniest sketch comedy series in person, Denver has a vast and crowded field of entertainment options this month. While a lion’s share of March’s comedy offerings are imported, there’s also a promising new free local showcase starting up. The fact that so many of these events take place in concert venues like the Gothic and Paramount Theaters is a testament to the drawing power of the headlining acts we have in town this month, as well as to Denver’s boundless hunger for comedic entertainment.
