yeah i've got that fennesz tape. it's not an album as such, just a kind of collage of samples he used in his early music. in fact, all of his stuff up until map ref was made on either an ensoniq eps16 or an asr10
both samplers were the first to implement loop-point modulation, or "transwaves" - invented by ensoniq as an attempt to replicate the wave table synthesis of the waldorf synth range, and used by countless artists to create glitches in audio. it allows you to essentially scrub an audio sample in realtime via lfo, mod wheel etc. jan jelinek's loop finding jazz records is another album that relies on this technique
supposedly if you were to set the loop-point to be modulated beyond the actual length of the sample, the sampler would spit out whatever memory was currently loaded into it's ram at random. you can hear this all over early autechre stuff
i just think it's so cool that the asr-10/eps 16 were used concurrently by underground electronica artists AND major rap/rnb producers ranging from rza to timbaland to kanye west
