For the conclusion of Gay Pride Week, a transgendered woman with a botched sex-change operation will belt rock ’n’ roll from the bottom of her “angry inch.”

The off-Broadway musical, “Hedwig and the Angry Inch,” will be performed tonight and tomorrow at the Granada, 1020 Massachusetts St.

“Hedwig” tells the story of a man who got a sex change to marry a soldier.

The operation goes awry, and leaves Hedwig with an inch-long penis.

To complicate matters, rock star and ex-lover Tommy Gnosis leaves him and takes all of his songs.

Hedwig then forms his own band and tries to chase down his ex-flame.

This musical brings two groups together: rockers and musical theatre lovers, said Barbara Eubanks, co-producer.

“It has poignant theatre moments interspersed with great rock music,” Eubanks said.

There is some trouble bringing the two together, said Steven Eubanks, director of the musical.

“It’s interesting to attract theatre audience to a hard rock show and hard rock lovers to come to a theatre show,” he said. “It’s a throwback to David Bowie and the glam rock era but the audience has to invest a lot of time into the monologues.”

Thanks to word of mouth, “Hedwig” is gaining a cult following much like another gender-bending show, “Rocky Horror Picture Show,” Eubanks said.

This event is co-sponsored by Queers and Allies.

“A lot of that interest came from the group,” Eubank said. “They have been getting a lot of buzz for us.”

The musical, which made its debut in 1998, was adapted into a film in 2001 and won the Sundance Film Festival Audience Award.

There are more songs in the stage version of Hedwig than in the movie, Eubank said.

“This show is more personalized for Lawrence,” she said. “There’s ad-libbing and Hedwig goes into the audience.”

Showtimes are 8 and 11:30 tonight and 11:30 tomorrow night. Tickets cost $15.
