NEW YORK — The assignment was daunting: Write a song for an onstage moment of transcendence. Make it kind of funny and exciting and for a five-piece band. Write it so it justifies an audience sitting in their seats for two hours before they hear it. And, oh, it must plausibly be a rock hit in 1976.
That was the job facing singer-songwriter Will Butler and the music arrangers for just one of the songs that stud the Tony Award-nominated play ''Stereophonic,'' a leading contender at Sunday's Tony Awards.
''It's like, ‘OK, that is a lot of things to think about, but let's just try it out and we just tried it out,''' says Butler, who left Arcade Fire in 2022 and has a new band, Sister Squares.
''Stereophonic'' is playwright David Adjmi's story of a Fleetwood Mac-like band in the mid-'70s recording music over a life-changing year, with personal rifts opening and closing and then reopening.
The music that accompanies the drama includes full-on rockers like ''Masquerade'' and ''Drive'' but also fragments and demos as the band reworks tunes. It is a wonderful slice of funky, classic rock for a fictional band that became a real one onstage.
''I was trying to get in their heads. I was also a lot of the time just trying to make a great song, which is a hard enough task. And then hopefully a great song can support many interpretations — that's the dream,'' Butler says.
Butler was connected with Adjmi by a mutual friend, and they first met at a diner about 10 years ago. Butler had just moved to New York and writing for theater intrigued him. It was a relaxed meeting and they hit it off: The two talked about ''Moby Dick'' for an hour.
Adjmi hadn't yet written a word of ''Stereophonic.'' He had the title, a vague concept and wanted it set in a recording studio. Butler over the next five years would submit ''random'' demos, like a song that someone might write if they listened to Phil Spector all day or one inspired by Sylvester in 1973 in San Francisco.
