Mystery to Me was Fleetwood Mac's last album recorded in England, the last to have two guitarists in the line-up until
Behind the Mask and the last to be co-produced and/or engineered by
Martin Birch. As with the preceding
Penguin, the group recorded the album at Benifold, their communal house in
Hampshire, with the
Rolling Stones Mobile Studio. Mick Fleetwood commented in a 2003 interview with
Modern Drummer that this recording situation proved to be cost-effective and gave the band more flexibility to record when they found it appropriate. The recording equipment was positioned inside two rooms on the first floor of the house, with cables leading into the front door of the mobile studio. Fleetwood described the outdoor acoustics as "just massive, like a concert hall, resounding off the trees and all through the grounds."
Dave Walker was asked to leave during the sessions and did not feature in any capacity on the final release. The album's name comes from a line in the chorus of "Emerald Eyes". "
Hypnotized" was a minor US radio hit and continued to receive airplay on
FM radio after Welch's departure. "Forever" is one of only two Fleetwood Mac tracks to feature Bob Weston as a composer and one of only a small handful to feature John McVie in this capacity. "Keep On Going" was written by Bob Welch but sung by Christine McVie because Welch decided her voice was better suited to the song. This was one of very few occasions when a member of Fleetwood Mac sang a song composed by another member. Although Fleetwood Mac's version of "Good Things" would not see release until 2020, it was later re-recorded by Welch with different lyrics and released as "Don't Wait Too Long" on his solo album
Three Hearts. "Just Crazy Love" was performed by Christine McVie on her solo tour in 1984. Early shows of the 2018–19
An Evening with Fleetwood Mac tour also featured "Hypnotized". Welch would re-record five of his contributions to the album – "Emerald Eyes", "Hypnotized" and "Miles Away" appeared on
His Fleetwood Mac Years & Beyond in 2003 and "The City" and "Somebody" were included on
its follow-up volume in 2006, although the latter only featured on the digital edition. ==Critical reception==
