Saturday-Sunday. Lately, we’ve been recommending a lot of offerings by the Colorado Symphony Orchestra — for a good reason. The CSO is trying some interesting things this season, and we want to get the word out. This weekend, the musicians join with the Colorado Symphony Orchestra Chorus and talented out-of-town singers for a staging of Gilbert & Sullivan’s “H.M.S. Pinafore.” While the comic opera is one of the most performed works in history, it rarely gets offered around here, at least with such credible players and singers. The 1878 work takes place aboard a ship where a captain’s daughter must choose between love and duty. 7:30 p.m. Saturday and 1 p.m. Sunday. Boettcher Concert Hall, Denver Performing Arts Complex, $25-$89. 303-623-7876 or .
