This new compilation called Carbon on Mirex is the best comp of hard/dark/heavy breakcore I've heard. New/exclusive tracks from Hecate, Xanopticon, Fanny, Donna Summer, Sickboy, Duran Duran Duran, Terminal 11, Subskan, Axiome and a bunch more.
If you're into the whole VSnares/Xanopticon style, you'd be wise to track this one down.
