Wanted to get the jump on this since February 18th of next year marks the 20th anniversary of Geogaddi. Figured it'd be a good place to post theories if they're going to do anything for it, as well as appreciation for this fine album. Here goes both for me:
Appreciation: It might be the BOC fanboy in me talking, but Geogaddi to me, is not only the best album BOC ever released, it's the best album Warp ever released. As the Pitchfork article for MHTRTC's 20th anniversary states, Geogaddi intensified the sound of MHTRTC, pushing it to its limits in an aggressive and highly conceptual level. For me, the whole album works as one cohesive adventure with nearly every song being on the same level of high quality and inventiveness. It's also get the best vignettes to ever be featured on a BOC album and they are of the same quality as the full length compositions. Perhaps the reason BOC changed up their approach with Headphase, is because they had pushed the maximum potential of the initial electronic sound of Music.
Theory for the 20th Anniversary: I think there's a greater potential for an expanded Geogaddi deluxe album because of how they famously said there's 300 tracks on the cutting room floor that they had to sort through to create the best possible album (which they succeeded with.) They never really said anything about outtakes from Music (except the acoustic album which they claim was lame) and IABPOITC was merely a conceptual "dumping" ep from the Geogaddi sessions of tracks that worked together. If Squarepusher's Feed Me Weird Things can get an expanded reissue for a 25th anniversary, then there is quite the possibility we can get an expanded Geogaddi.
Either that or more t-shirts and a print.
