Task: Question Generation
Input (English): Passage: In 2012, American songwriter and record producer Benny Blanco met with Norwegian production duo StarGate at a recording studio in New York City to write new songs, including one for Rihanna. StarGate had previously produced her singles "Don't Stop the Music" (2007) and "Only Girl (In the World)" (2010). According to Blanco, he and StarGate wanted to deviate from Rihanna's usual sound and produce as though the song would be for a rapper such as Kanye West: "It's the one that we weren't thinking Rihanna ... that turned into the Rihanna record ... But that's how it always happens like with me". They produced the song's drum machine beat after the other instrumental music was recorded.StarGate's Mikkel Eriksen told The New York Times that Blanco took a recorded snippet of Eriksen's singing, altered it electronically, and made it sound "dirtier". He then applied timbre and used audio software to create ghostly accompaniment lines. Eriksen described Blanco's style as "unorthodox, as he almost never plays the keyboards but throws in weird samples and alters them to the right pitch to go with the song." Australian singer-songwriter Sia later joined them and wrote the lyrics for "Diamonds" in 14 minutes.After the song was completed, they wanted to play it to Rihanna, but Blanco was skeptical about the reaction towards the song because of its slow sound. After StarGate played it to her, they called Blanco from London and told him that she liked the song: "She's flippin' out. She played it like seven times in a row. It's her favorite song." Phil Tan and the assistant Daniela Rivera, mixed and mastered "Diamonds". Recalling it, in an interview with The Huffington Post, Blanco commented, "we needed to have it recorded, the beat finished, mixed and mastered in 24 hours. She was recording in a separate part of the world, sending back the files, we're finishing the music and then we're mixing and mastering it, and then it was out in a few days. It's fucking amazing and incredible." Kuk Harrell produced Rihanna's vocals on the song and recorded them together with Marcos Tovar.
