Moreover, I (unfoundedly) suspect that Cap.IV may have been the original closer for Confield. The similarity of both tracks and also the nearly identical runtimes (so it could also fit on the CD?). Maybe the boys deemed it a bit too wild for the album, but didn't want to ditch the idea. Hence, a similar track, but somewhat more in line with the general atmosphere of the album. Too good a track to let go to waste, it was perfect for an EP.
I believe I've read somewhere on WATMM that Gantz Graf (the track) was made in 1997 or so and was something they didn't know what to do with. So together with this and Dial. it made a smashing EP. Perhaps Dial. is the only track specifically written for that release?
Could be total bollocks though...
