I'll agree with earlier posts that "techno" enjoyed a brief stint as poster child for electronic music in some magazines - and then it faded back dow to the dedicated niche following that it's enjoyed for years. When I think of techno I think of Derrick May, Drexciya, Tresor label, Richie Hawtin, Speedy J, and all the fun dubby goodness that's been mentioned already from the Basic Channel, Chain Reaction labels and the more recent Deepchord and Echospace stuff currently. In fact - the Basic Channel CD comp is playing at my desk here at work right now...
I kind of get all the IDM, dnb, techno, and just generally electronic stuff all blurred in my head anyway - they all sort of push and pull each other anyway. The "big beat" stuff like Chemical Brothers - yeah - Surrender - there are some brilliant tracks on that one. I stopped buying after that (but I pretty much cut waaaay back on any cd buys after that).
Crystal Method - "Vegas" is a brilliant album - and there are moments from Tweekend and Legions of Boom that are very nice.
Underworld - there isn't much I don't like from them - always good -even the post-Emmerson stuff - though I tend to like the dubnobass through beaucoup fish stuff best.
IDM-land... definitely a fan of a lot of the 90's era Warp and Warp-like stuff - Two Lone Swordsmen, Autechre, Richard H. Kirk, The Black Dog / Plaid, etc. etc. etc..
