Shinko tends to be hit and miss with their band scores, but Q.E.D. is a good step in the right direction. The meat of each song is transcribed faithfully, but once you have to repeat sections, sometimes the variations aren't notated, which means you'd have to figure it out by ear. Some songs, like 'Maria,' suffer from this since the bass lines aren't that audible, which would make it troublesome to actually figure it out. '20+∞ Century Boys' is one of the worst transcriptions I've seen. I have the Fairy band piece for the song, and it's a lot more detailed than the one found in Q.E.D. when compared side-by-side.

In any case, it's good that there's at least a band score out for this album because there are tons of layers in the song that would be inaudible and indiscernable if it wasn't for this score. While not one of Shinko's most outstanding efforts, it's at best an average band score. Hopefully they keep improving their products like they have been for years now.
