Sia Gets Real About Being Stood Up by Kanye West and Rihanna

While promoting her new album, This Is Acting, Sia sat down for a rather revealing interview with Rolling Stone—where she pretty much laid bare every fascinating piece of gossip the music industry has to offer.
Although the singer-songwriter has worked with every major recording artist there is, she had some pretty interesting things to say specifically about the unexpectedly flaky Rihanna and Kanye West.
On being stood up by Kanye West and Rihanna: ​"They'll entice me into a session by saying, 'Rihanna will definitely be there' or 'Kanye will definitely be there,' but it's hilarious because I turn up and, almost always, they never come.
So I went into the studio to write for Rihanna with Kanye and neither of them showed up and stayed for less than an hour.
They had two tracks.
They told me what they had wanted.
There were notes from Kanye, and I can't even remember what they were.
I remember I just raced in and raced out, and I thought there was something about the chorus that seemed fun about this song, but I never thought it would see the light of day.
My manager pushed for this song ['Reaper'] to be on the record, but I don't care about it."
