Please answer the following question: Given the following context:  Aaliyah began recording the album in 1998. She recorded a few songs, including two with longtime collaborator Timbaland, before working on Romeo Must Die. In 1999, while working on the record in New York City, Aaliyah called and asked Trent Reznor, one of her musical idols, to produce a song, but they could not coordinate their schedules. She intended to finish the album by the end of 2000 and resumed its recording while filming in Australia for Queen of the Damned (2002), as she shot her part for the film during the day and recorded songs at night. She said in an interview for Billboard, "there were nights when I didn't go into the studio—I was too tired. On the weekends, I always made it." Jomo Hankerson, Blackground president and Aaliyah's cousin, said that he had to "bribe the producers", who did not want to "go halfway around the world!" He added that they ultimately had "a beautiful time ... making hot music".Most of the album's songs were recorded at either Sony Studios in New York City or Sing Sing Studios in Melbourne, including "Loose Rap", which was done at both studios. Aaliyah recorded "More Than a Woman" at Manhattan Center Studios, "U Got Nerve" at Soundtracks Studios in New York City, "We Need a Resolution" at Westlake Studios, and "I Care 4 U" at Magic Mix Studios and Music Grinder Studios in Los Angeles. She had first recorded "I Care 4 U", written by past collaborator Missy Elliott, in 1996 for One in a Million, but scrapped it after that album's completion. Aaliyah worked with Blackground Records' in-house crew of musicians, songwriters, and producers, including novice producers Bud'da, J. Dub, Rapture, and Eric Seats. Music manager Jimmy Henchman, a friend of Aaliyah's manager Barry Hankerson, helped coordinate the record's production and arranged for the producers and writers to work with the singer.  answer the following question:  What are the full names of the people who could not coordinate their schedules?
A:
Aaliyah
