The Weathermen - 909 Backup - Boscaland BOSC039
http://www.discogs.com/release/47058
Love the busy drumbeat and deep bassline.

Punk Floyd - The E's Are Working (Coming Up Mix) - Smitten Remix SRX4

DTD and Chris Lib slow it down but crank up the funk.

Secret Hero - Control (original) - Stay Up Forever SUF18
http://www.discogs.com/release/31670
Builds and builds and builds, then lets rip. The tune that introduced me to acid techno.

A+E Dept - Experiment IV (original) - Stay Up Forever SUF23
http://www.discogs.com/release/23483
Has everything - chugging bassline, throbbing 303, cool samples, the best breakdown I've ever heard and a finale to die for. Intense.

Secret Hero - Multiform/Speedfreak (both original) - Stay Up Forever SUF26
http://www.discogs.com/release/31660
Two total classics in one package. Speedfreak has everything I love about acid techno and the 303 finale to Multiform is fantastic.

Overrider - Timebomb - Choci's Chewns CC025
http://www.discogs.com/release/254520
Tick tock tick tock tick tock boooooom - a DDR classic.

Ha-Lo - Dirty F***ing House - Deluxe 004-6
http://www.discogs.com/release/227711
Chris Lib and DTD again - tech house it may be, but I like it cos it chugs along nicely and is different from the norm.

There are plenty of others but that'll do for starters. What's my favourite from that little lot? It's a toss-up between 909 Backup and Experiment IV.
