Ok, how about
Chicago (aka
Chicago II) instead?
Given how much remix work Steven Wilson has done for Warners lately (and the fact that they just issued an Atmos/quad version of
Chicago IX: Chicago's Greatest Hits so they're clearly open to doing Chicago) is it a stretch to see them reaching out to Wilson to do an Atmos mix, especially since all the heavy lifting was already done in 2017 when he did the stereo remix?
There are so many mixes/mix variants you could put on a Blu-Ray:
1970 2.0 Stereo
1974 2.0 SQ Quad
2003 2.0 Stereo (Klingberg mix, the HDTracks version that doesn't have the DVD-A mastering compression)
2017 2.0 Stereo (Steven Wilson mix)
2024 2.0 Stereo (SW revised mix)
2024 2.0 Instrumental (SW)
1974 4.0 Quad Mix
2003 5.1 Mix (Klingberg, remastered/unmastered)
2024 Atmos Mix
Add that in, along with single edits, mono mixes, demos, and if you're really feeling spicy, add in the 1970 Tanglewood, MA show from that tour from Wolfgang's Vault (on YouTube
here) and you have the makings of a very nice "expanded/deluxe-ish reissue of a classic rock album."
