I'll let you in on a secret that might help you to decide whether to buy this album ("MiniDisc" by Gescom, a/k/a Autechre): Most tracks are so short that hitting *continuous play* on the Amazon playlist will practically let you hear the entire thing first.
Now you can make up your own mind without having to listen to anyone else's opinon. That said, if you'd like to know what I think, here's my take:
I like nearly all of Autechre's music, but the most abstract and abrasive tracks are my favorites. For me, Untilted, Draft 7.30 and Ganz Graf are just as enjoyable as Chiastic Slide or Tri Repetae.
MiniDisc is a much earlier foray into Autechre's difficult style. It precedes Untilted and others by several years. As an earlier example of Ae's difficulty, MiniDisc is fascinating: Booth and Brown recommended the album be listened to in gapless shuffle mode. On this one album, Ae were only thinking about microstructure and letting the shuffle function of minidisc players handle the macrostructure. For that reason, MiniDisc doesn't "flow" in the way their longer pieces do: it jerks and inches and spasms along, which is exactly what Booth and Brown intended.
That said, MiniDisc is an abstract album I love and respect. It has a kind of perfect integrity as an artifact, and the pieces are so isolated that listener participation needn't stop at random play. You could easily combine and edit tracks to make a new album out of this and have it sound completely different from the source material. MiniDisc is like a set of tools for a DJ mix on a planet where DJ mixes are "beatless" (meaning they never settle into any one meter).
I'd be lying if I said I was sure you'd like MiniDisc as much as I do. To be fair, some Ae fans seem not to care for this album. One listener on Amazon actually dismissed MiniDisc as a "minor work," which seems a bit presumptuous (what are we, musicologists?).
As far as I know, MiniDisc is the only full-length album Ae made under the name Gescom. That alone makes it "major," not "minor." Why confuse individual preferences for an objective method of classification? A collection of eighty-eight tracks, no matter how short, can't be anything but major.
No, MiniDisc isn't as linear as a normal album. But that's because it isn't supposed to be. We have other albums in our collections for that. This one's doing something very different (and very welcome).
