2003 Surround-sound Remix
In 2003, Virgin reissued Avalon on Hybrid Super Audio CD with a new 5.1-channel surround sound remix by the original production team of Rhett Davies (the producer) and Bob Clearmountain (the mixing engineer). The original 1982 stereo mix is left intact and is the same for the CD layer and for the HD layer, allegedly being transferred from analogue master tapes to DSD and processed in DSD throughout the process. The surround part of the HD layer includes the full album in the original running order plus the bonus track "Always Unknowing", whose original stereo mix is only available on CD on the 4-CD boxed set "The Thrill of It All" and in the 2012 complete recordings box set.
Except for "India," the short instrumental piece whose original multi-track tape had been lost, all tracks in the surround mix were remixed from multi-track sources, as opposed to two-channel stereo mixes being 'upmixed' to 5.1 as in some DVD-Video releases. For "India," the stereo mix is panned clockwise a few times as the piece is being played, which ends in the rear right channel, from which the saxophone begins the next piece, "While My Heart Is Still Beating," making up for "India" not being a fully-fledged surround recording. The surround mix has roughly the same running times as the ten tracks present in the stereo mix. The main difference is in the stereo image being 360-degrees wide, as opposed to a front image plus rear ambiance, and the levels at which various tracks from the multi-track are mixed into the multi-channel mix. For instance, the guitar parts in "The Main Thing" and "Take a Chance With Me" are noticeably more prominent in the multi-channel mix than in the stereo mix. Guitar, saxophone, synthesizer, and percussion parts are often placed in the rear part of the sound field, while lead vocals tend to stick to the front centre, as opposed to being mixed in dual-mono in front left and right like in the somewhat traditional 2.0 stereo mixing.
