BALLARAT Light Opera Company (BLOC) has put the finishing touches on its production of one of Broadway's most-loved musicals.

BLOC held a full dress rehearsal of Chicago on Wednesday night ahead of its opening on Thursday.

The musical vaudeville tells the story of the merry murderesses of Cook County Jail who are awaiting trial for their crimes.

Co-production manager Claire Thorpe previously said audiences could expect great music, great songs and a lot of dancing.

"The music director is Ian Govan ... he has done multiple shows with us and is a music teacher at Ballarat Grammar," she said.

"It's very bright and there are beautiful costumes."

The Ballarat production brings together local musical theatre talents including Leah Delaland as Roxy and Vanessa Stephenson as Velma. 

Chicago's opening night on Thursday will see $5 from every ticket sold donated to the Friends of Ballarat District Nurses and Health charity.
