In electronic music, Autechre is your friend. Especially post-millennial Autechre. Also check out Venetian Snares and Arca.

Gree with VSnares and Autechre. Never heard of Arca, will check them out.

Arca has incredible otherworldly production, but, I would say, is mostly harmonically grounded in pop music and opera. Strange bedfellows, but if you listen to his newest self-titled album it makes sense that he mixes pop harmonies with IDM production with operatic drama.

In short, Arca is an incredible musical experience but not really in the way that it seems you're asking for.

Almost all electronic music is basically pop music without vocals. I think we've actually taken a huge backward step in experimental music since the 70's or so. Everything got very conventional and pop influenced towards the 80's - and it has remained so ever since. There are notable exceptions like autechre - who continue to actually let experimentation and concepts be the leading light - and other small sub groups of musicians that operate very much on the sidelines. Ricardo Villalobos would be another well known figure who genuinely experiments.

I find Arca to be all style and no substance. I don't think he will be remembered at all in years to come.

But it's an impressive style.

I agree with you, but there's no telling what the OP will like, and variety spice yadda yadda.

Absolutely. Arca does seem to impress many folks.
