Justin Tranter says he doesn't know how 'Grease: Rise of the Pink Ladies' music going to work

 Justin Tranter spoke about the music he wrote for "Grease: Rise of the Pink Ladies" in a latest interview with Reuters.

Tranter has attained success by penning hit pop anthems like Justin Bieber's "Sorry" and Imagine Dragons' "Believer,".

"I'm very proud of my pop songs but there isn't the level of storytelling that's required for a musical," Tranter told Reuters.

"Some of it feels very true to the '50s and some of it is very much a late '70s take," Tranter said, referring to the original "Grease."

He also wanted to bring some of his contemporary pop style into the mix as well.

"We are waiting to see how an audience receives 30 original songs over 10 episodes. No-one has done it before so we don't know how it's going to work," Tranter said.

For the 10-part musical TV series based on the famous 1978 film "Grease," Tranter wrote 30 original tracks - most of which weren't in the vein of the pop songs for which he is known.

"Grease: Rise of the Pink Ladies" is set in 1954, four years before the story of the U.S. high school movie starring John Travolta and Olivia Newton-John.

The first season, which ends on Thursday, follows four rebellious students who unite to become the misfits of Rydell High and eventually the "Pink Ladies" clique. The show's lead, Marisa Davila, portrays Jane Facciano, the first female student to run for class president.

When he knew he was interested in being a part of the project, Tranter wrote his own original audition song, "Too Cool," which is featured in the first episode.

One of the main challenges Tranter faced was emulating the popular songs from the original film, which incorporated sounds from different decades.
