The 45th anniversary Sierra Repertory Theatre season is in full swing with surprises around every corner.

The deviously delicious Broadway and Hollywood sci-fi smash musical, “Little Shop of Horrors” has devoured the hearts of theatre goers for over 30 years and will entrance local audiences through April 28 at the Fallen House Theatre in Columbia State Historic Park.

The meek floral assistant Seymour Krelborn stumbles across a new breed of plant he names “Audrey II” – after his coworker crush. This foul-mouthed, R&B-singing carnivore promises unending fame and fortune to the down and out Krelborn as long as he keeps feeding it, blood. Over time, though, Seymour discovers Audrey II’s out of this world origins and intent towards global domination.

Starting May 9 and running through June 9, “The Drowsy Chaperone” will be playing at the East Sonora Theatre.

Hailed as “The Perfect Broadway Musical,” it is a loving send-up of the Golden Age musical, featuring one show-stopping song and dance number after another. When a die-hard theatre fan plays his favorite cast album, the characters come to life in this hilarious Tony Award-winning musical farce.

Take a dollop of Grease, mix in some Pump Boys and Dinettes, and add a generous dose of Forever Plaid and you’ve got the high-octane fun of “Route 66.” This show features songs from the ‘Main Street of America’ from Chicago to the California coast with the greatest ‘Rock ‘n’ Road’ hits including “King of the Road,” “Little Old Lady from Pasadena,” “Fun, Fun, Fun,” and many more.

“Route 66” will be at the Fallon House Theatre from June 20 through July 21.
