question: Who is so fast and good at what she does that you can't afford to waste time on anything?
context: She's so fast and good at what she does that you can't afford to waste time on anything, so if we're ready to record drums, for example, we're going to work with whatever we have available right there and then. That's why we worked in such great studios, because we know they have great gear, and we don't need to worry about renting gear. Part of my job as an engineer is to make sure the sessions are not only moving along, but moving along at her pace.
  After the move to MSR, Beyoncé and her production team began travelling. In the United Kingdom, they worked at Peter Gabriel's Real World Studios in Wiltshire—particularly using Gabriel's multi-instrument room—to create "Love on Top". Soon after, Beyoncé joined Jay-Z in a Sydney mansion, as he was working on his collaboration album Watch the Throne (2011) with Kanye West. There they created a "primitive studio" using a microphone, a rig out and Pro Tools software to record. Sessions were also held in Las Vegas, Los Angeles, Atlanta and Honolulu.In February 2011, MTV reported the project was nearing completion. 4 was mixed mostly at MixStar Studios in Virginia and mastered at Sterling Sound in New York City. The audio mastering was delayed by a week following the unexpected recording of "I Was Here". Diane Warren had played the song to Jay-Z during a telephone conversation, leading him to put Warren and Beyoncé in contact. In May 2011, Beyoncé submitted seventy-two songs in preparation for the album's release. According to Swivel, an eclectic range of songs were recorded, including ballads, "weird ethereal things" and 1990's R&B and Afrobeat-inspired songs. Columbia Records were reportedly overwhelmed with the "sheer volume of material she presented to them".
