"I’m going to talk about the works in this CD. It includes CIRCUIT I and CIRCUIT III, they belong to the CIRCUIT series”. CIRCUIT II was included in my "Electronic Works vol.1. I’m going to explain for those people who don’t know the "Works vol.1”. In the series of electronic music entitled CIRCUIT, the next work is created using the material from the previous one. At first I burn the precious CD into two CDRs, next I cross them and make new CIRCUIT music by using two CD-J players. Since this operation can be continued forever, CIRCUIT IV will be created by multiplying CIRCUIT III in the future. This series can be listened to on its own, but it would be interesting to compare it with the previous one or the next one. Since the material is the same, you will hear the same kind of sound, but in some cases, it may be completely transformed, and in other cases, it may remain the same. If you listen to this CD alone, you may feel that the change between CIRCUIT I and CIRCUIT III is significant, because CIRCUIT II is missing. In addition, there are many improvisational elements that intervene in the multiplication of this CIRCUIT series, and although it can be performed live, the result will be different each time it is performed.

Therefore, the only identifiability of the work lies in the fact that it was created from the same material. For example, if CIRCUIT III were to be performed somewhere in the future based on CIRCUIT II, it would be different (but roughly similar) to CIRCUIT III on this CD. In other words, unlike fixed electronic music, there is no definitive version of a work, and multiple versions of a work are created from time to time. Thus, the CIRCUIT series on CD is also not a definitive version, but a version from time to time. 

Creeps and Fil were composed in 2001 and 2005, respectively, and have never been released publicly. I don't remember the details of Creeps because I composed it so long time ago, but I remember I made it using a Roland VS-1680 digital MTR, which I often used at that time. This piece belongs to an unusual trend in my electronic music: music that people observes its minimal repetition and gradual changes in noise.

Fil is not at all similar to Creeps, it’s partly because they have originally different direction, but also because I started to use CD-J during this period. The change in equipment used has a profound effect on the concept. This CD-J line has continued to this day, and in that respect, Fil is broadly similar to the way the CIRCUIT series was created.

Only Transmitted Light is not electronic music, but an electrone* piece. This piece was commissioned and premiered by Yukino Ichikawa in 2017. If this piece sounds so peculiar in this CD, it is not because it is instrumental music, but because it is a different line from the other pieces. I won't bore you with the details, but I have recently been referring to this line as "elastic series”. It is completely different music from Creeps, but they were both influenced by Steve Reich. Come to think of it, I've never composed ‘elastic’ electronic music yet, so I will try to make it some next time."  - Haruyuki Suzuki
