Fans of flavorful and funky craft beer are sure to flock to the SoWa Power Station (540 Harrison Ave.) in the South End on September 22 & 23 for the second annual Copenhagen Beer & Music Festival. Consisting of three sessions, the sudsy, Denmark-inspired celebration boasts special concoctions produced by more than 50 breweries from both near and far, including those of local purveyors Night Shift, Trillium and Lord Hobo. Not to forget the music half of the fest, Danish surf rockers The Tremolo Beer Gut perform along with several Boston-based artists. And to top it all off, expect plenty of great grub from some of the city’s finest vendors, including Roxy's Grilled Cheese and Tasty Burger.
