Top Ten Electronic/alternative Albums

agreed on aphex twin's selected ambient II (most his stuff is good to great, with a few exceptions)

clouddead- ten
boards of canada- music has a right to the children
can- tago mago (although my friend said this was top ten music went it was released in germany- so it is not exactly alternative)

nurse with wound- spiral insana
hood- cold house- interesting version of early 90s british drone rock, electronics and hiphop

my bloody valentine- glider ep
olivia tremor control- black forest
autechre- chiastic slide
miles davis- panthalassa (while their are many good lps from miles' fusion period, this is an excellent remix by jack of all trades producer bill laswell using the best tracks of miles' fusion period)

Speaking of old stuff from the 70's..
klaus schulze released an album called "moondawn" in like 1973.. it is pretty analogue sounding but trance music none the less. similar but not exactly like some of the material released currently or in the 90s.. according to one web site, moondawn is the most accessible album for the american audience being that it was widely released states side in the 70s..

in other kraut bands.. the album zeit by tangerine dream is quite a classic.. some realllly wicked manipulations done to audio on that one.. again it is like early 70s..

but these albums are more on the avantgard tip instead of the alternative tip.. not that there is much of a distinction between the two but to me it is noticable...
