NEW YORK — Margaret Cho combines comedy with music on her new album to address some somber topics: rejection, interventions and even murder.

“Cho Dependent,” which the comedian describes as “jokes written in song form but with incredible artists,” came together with the help of musicians including Ben Lee and Fiona Apple.

Folk rocker Andrew Bird helped with a song about a former love interest turned murderer that Cho said is based on her life. For 17 years, she said, she carried a torch for a man. She lost touch with him and eventually looked him up online and was shocked to find he’d been convicted of murdering his wife.

“So, it’s a good thing we didn’t hook up,” the comedian said.

Writing a song about such horrific events was cathartic, Cho said. “The worst things, the most tragic stuff in life can actually, strangely be hilarious.”

Cho has released seven comedy albums, but “Cho Dependent” is the first where she sings.

The album also features an intervention put to music with Canadian rock band Tegan and Sara.

Its lyrics include, “Welcome to your intervention. We need some of your attention. You’ve got a problem we must mention.”

“Cho Dependent” was released last week.
