SALT LAKE CITY — Want to stay inside? We’ve got you. Need some fresh air? Look no further. Maybe a movie strikes your fancy. Perhaps some live music, or a bike ride, or an art gallery. In this installment of Your Weekend, we leave no downtown activity unexamined. Let’s get to it.

RiffTrax Live: ‘Space Mutiny’

Get ready for a movie so bad it might actually be good. RiffTrax Live tackles the 1988 sci-fi opera “Space Mutiny” — “one of the most hysterical cheeseball movies to ever come out of the ’80s,” according to RiffTrax’s description. The trailer speaks for itself. June 14, 7 p.m., various theaters, prices vary (fathomevents.com).

Jon Batiste at the Gallivan Center

Downtown’s Gallivan Center celebrates its 25th anniversary with a concert featuring Jon Batiste (bandleader of “The Late Show with Stephen Colbert”), the Philip Kuehn Orchestra and various local jazz artists. In addition to the “Late Show” gig, Batiste is also creative director of the National Jazz Museum in Harlem. Seriously, where does this guy find the time? June 15, 7:30 p.m., 239 S.
