the Back to the Future film soundtrack. Buckingham retained Droman to engineer what was intended to be his third solo album, although the project eventually morphed into a Fleetwood Mac album once other members got involved. Dashut and Droman recalled that the album's recording sessions were particularly tedious, even by Fleetwood Mac standards. At one point, they experimented with slowing down songs in order to find suitable textures. Sometimes, this would double the song duration, which made for "a brutal ten minutes to listen to", according to Droman. By tripling and quadrupling these mixes, they managed to make each song sound "open and airy". Although the record took eighteen months to complete, Stevie Nicks spent a total of two weeks in the studio with the band, as she was promoting her third solo record, Rock a Little, throughout this period. Nicks sent demos of her songs to the band, recorded while she was on tour, for them to work on in her absence. "Welcome to the Room... Sara" was inspired by her thirty-day stay at the Betty Ford Center to overcome her cocaine addiction in October 1986 (Nicks used the pseudonym "Sara Anderson" when she checked into the facility). When Nicks did go to the studio, she often felt unmotivated: "I can remember going up there and not being happy to even be there... I didn't go very often". Vocal sessions took place in Buckingham's master bedroom, where Nicks frequently recorded her parts for Buckingham and McVie's songs under the influence of alcohol; Buckingham deleted most of Nicks' vocals after she left the studio. "I'm not blaming him for that because I'm sure they totally sucked. Vocals done when you're crazy and drinking a cup of brandy probably aren't usually going to be great". Buckingham recorded some of the vocals using a Fairlight, an early sampling synthesizer. On "When I See You Again", he re-assembled separately recorded takes of Nicks, explaining, "I had to pull performances out of words and lines and make parts that sounded like her that weren't her". "That was in my estimation when everybody in the band was personally at their worst. By the time we did Tango in the Night, everybody was leading their lives in a way that they would not be too proud of today". With pressure on Buckingham to keep the project focused and moving forward, things came to a head shortly
