Astoria — The Liberty Theater presents the vocal illusions of comedic ventriloquist Lynn Trefzger at 7 p.m. Thursday, April 16.

Trefzger, a self-taught ventriloquist, brings together figure manipulation and vocal skills to create a comedy act that delights young and old. Writing and developing her endlessly inventive routines, Trefzger thrives on her interaction with the audience.

Trefzger has been performing since 1977. Her agile brain and even quicker fingers give her the ability to individualize her performance for each group she entertains. Dummies, puppets, inanimate objects and by-standers become part of the show.

Her vocal talents were first brought to national audiences on “Star Search,” and she has since performed with artists including Jeff Foxworthy, Ray Romano, Drew Carey and Faith Hill. Her off-the-wall audience interplay is riotously funny, and her performances are tailored for both family and adult audiences. Trefzger has appeared on ABC, TNN, A&E and Lifetime.

Fact: Your voice is not necessarily your own when you’re in an audience for Trefzger’s show. You could find yourself next to a rather inebriated camel — or with a new baby you didn’t even realize you had.

Warning: Be extra nice to her old man Judd. He’s a cantankerous old man, and he holds little back.

Tickets for the show are $15 for adults and $12 for students, seniors and military, $5 for children. Tickets are available at the box office located at 1203 Commercial from 2 to 5:30 p.m. Tuesday through Saturday and two hours before the show. For information, call 503-325-5922.
