Mght Music You can Escape at the Legacy If you've begun to feel the winds of winter creep under the doorsill, it might be time to slip into a warm night spot and dance up a pulse-racing pulse-racing storm. The Legacy Social Club, on upper Main Street next door to the Dudler Building, invites you to Escape with the music of a rock-and-roll band. And that's just one musical vacation that beckons this week. BajaCantina The Baja Cantina, at the base of the steps that lead to the plaza at the Park City Ski Area, is more than a Mexican food stop. Every Thursday night you can munch your chips and salsa to down-home music with the accent on home. Locals' night brings a parade of amateur musicians into the limelight from 9 p.m. to closing. You are welcome to break open your instrument case and sit in. Or just break out the margaritas and give a listen. Down Under Folk singer Kat James is as much a staple as baseball steaks at the Down Under club in the basement of the Claimjumper restaurant and hotel on lower Main Street. And there's a good reason. Her kind of music never seems to go out of style. She tunes up her guitar about 9 p.m. and plays until midnight. Grub Steak Diners at the Grub Steak restaurant in Prospector Square will find the music of Mark Milligan a welcome appetizer on Friday and Saturday from 7 to 11 p.m. Legacy Social Club You can beat feet with the stomp-and-sway sounds of Escape this . weekend at the Legacy on upper Main Street.
