Kendun was the go-to Mastering house for many top artists in the 1970s, including Fleetwood Mac. At Kendun, they used a room they called the Master-Room, which provided what they called Master-Room Reverberation. Kent Duncan once said: “What I like about Master-Room sound primarily is the relatively clean first order echo. It’s a real smooth system. We like it especially on electronic instruments, and the Master-Room can even take drums and sound good. It’s much better than any other comparable type reverb. Master-Room reverberation chambers provide the finest in Natural Sound Ambiance.
The Mac's first cohesive step toward the brilliance of their Pop Masterpieces to come. A beautiful if sublime album. This is the often overlooked era that included masterful songwriter Bob Welch.At this point, the band was best-known as a British blues unit. Slowly but surely the band was becoming more acclimated with a production style that was reminiscent of the California pop sound. With the majority of the blues and psychedelic behind them, Mystery to Me finds Fleetwood Mac in a more ruminative vein. American guitarist Bob Welch established that path. Despite the all-encompassing ethos, Welch's songwriting skills made him walk a fine line between the mystical and the silly. But luckily most everything works here. The leadoff song, the laid-back "Emerald Eyes" matches Welch's spacey lyrics and vocals as Christine McVie provides great backing help. The album's best track, the gorgeous and lyrically strong "Hypnotized" has Welch matching an effortless, soothing croon with jazzy guitar riffs. Throughout Mystery to Me the amazing and almost telepathic drums and bass of Mick Fleetwood and John McVie give this effort more panache and muscle than was represented on this effort's predecessor, Bare Trees. The best Bob Welch offering, "Keep on Going," has a strong, soulful string arrangement and Christine McVie's customary sensual and poised vocals. "For Your Love" is done in a post-psychedelic style. Mystery to Me's interesting sound is directly attributed to the fact that it was recorded on the Rolling Stones Mobile Unit. This effort is custom-made for those who like thoughtful offerings and is a valuable set in the scheme of the band.
