ross,
if you dig Gramm, by all means get Dettinger's Intershop -- there's quite a bit of crossover here, and the Dettineger is probably one of the most "soulful" releases I bought last year. skip Ihan's Iota -- it's mostly scree and noise, and not nearly as compelling. Alva Noto (carsten nicolai)'s Prototypes is brilliant -- somewhere right in between typical glitch exploration and something much more rhythmically/melodically inclined. i can't speak highly enough of this release.
