Warp Records circa 1995-1999 is a good place to start. Check out "Classics", which compiles the label's earlier bleepy techno, then check out the Artificial Intelligence series, then pick a random selection of Squarepusher, Autechre, and... was Venetian Snares on Warp?
I have an old book called Sampler: Contemporary Music Graphics, that was published in 1999 and is basically a fantastic who's who of all that was trendy back when I was young. I'm going to flip open a random page...
... and it's Ken Ishii, Echo Exit on the left and Add N to (X) on the right with Little Black Rocks in the Sun. I'd forgotten all about Add N to (X). They did Metal Fingers in my Body. Perhaps it's because that was my golden age, but I'm of the opinion that electronic music reached a peak in the late 1990s and hasn't topped it since; hip-hop mostly displaced the talent and the big names grew old. Flip another page...
... and it's Oval, Dok, which I had never heard of. Youtube reveals that it's glitchcore field recordings from 1998. Flipping another page I get GusGus, Polydistortion. It's a great book, £5 from the Notting Hill used books exchange.
