For upscale entertainment, it doesn’t get much classier than the remarkable Bass Performance Hall (555 Commerce St., 817/212-4200, www.basshall.com). Billed as the last great performance hall built in the 20th century, this stately facility is reminiscent of the classic European opera houses.

Architectural features include two enormous angels (48 feet tall) sculpted from Texas limestone on the building’s facade and a colorfully painted 80-foot-diameter “Great Dome” above the concert theater. Bass is home to the Fort Worth Symphony Orchestra, Texas Ballet Theater, Fort Worth Opera, and the Van Cliburn International Piano Competition. Visit the website for information about touring shows.

The improvisational comedy group Four Day Weekend (312 Houston St., 817/226-4329, www.fourdayweekend.com) traffics in interactive entertainment. The audience is invited to become part of the hilarity by submitting ideas for improv routines or by joining the cast on stage for short ad-lib routines. Video, music, and the cast’s sharp skills enhance this unpredictable experience. Shows are held Fridays and Saturdays at 7:30 p.m. and 10 p.m. Tickets are $20.
