The poolside panel took place at the American Association of Independent Music (A2IM) SynchUp event at the Annenberg Community Beach House on Thursday morning.
The panelists began by discussing how they set the atmosphere for their films through the soundtracks. For Alfonso Cuarón's Roma, which takes place in Mexico City during 1970 and 1971, Fainchtein spent a year and a half researching the songs that played over the radio during that time period.
"There was a magazine called Notitas Musicales, and Notitas Musicales used to release a weekly magazine of what was airing with the schedule for the TV and for the radio," Fainchtein said. "So the show that is airing on the TV when the family is together, it's the same show that was airing at 8 p.m. on that channel and we got the images."
Michel said that the first order of business for assembling the music for A Star Is Born was determining the sound of Bradley Cooper's character, Jackson Maine.
"It's the fourth incarnation of A Star Is Born ... [his sound] had to be contemporary but it still had to be like an aging rock star that could possibly have a hit today," Michel said.
Later on in the morning, the panelists spoke about some of the challenges of negotiating with artists and being able to afford to use their tracks. Jordan said he has lost relationships with filmmakers over songs that have been pitched to him, but ultimately withdrawn because the music rights couldn't be cleared.
"The other thing that we've run into is sometimes artists are just precious, and I've been in experiences with Julianne and by myself where we've had directors write letters to the artists and they still say no," Michel said.
Of the songs that are the hardest to clear, Led Zeppelin's "Stairway to Heaven" is the most impossible, Jordan said. He added that other difficult artists to clear include Kanye West, Jay-Z and Beyonce.
The panel ended by fielding questions from the audience, which comprised representatives from indie record labels and industry members. Throughout the day, A2IM SynchUp hosted other panels for indie and Latin music as well as indoor workshops.
