Question: who sings another day of sun in la la land

title: Another Day of Sun
text: The sequence -- the first of the film to be shot -- was filmed over two days in August 2015 , in temperatures over 100 degrees . The song was filmed on a 130 - foot - high express ramp of the Judge Harry Pregerson Interchange between the Harbor Freeway ( Interstate 110 ) and the Glenn Anderson Freeway ( Interstate 105 ) in South Los Angeles . The ramp was closed for the two full days of filming . The rest of the highway was left open , so that normal traffic is visible in the background . The sequence was initially planned to be on a ground - level ramp , but it was changed to the interchange to give a sense of the vastness of the city . Director Damien Chazelle also likened the number 's location on a highway to the Yellow Brick Road in The Wizard of Oz .
