Was about to start a breakcore thread, lol.
Warning: most (maybe all) of this stuff is drastically different from the jungle-y sound you posted. If this isn't what you're looking for, I'm really sorry!
Anyway, try checking out goreshit's bandcamp. He uploads a bunch of stuff on there (lolicore, idm, breakcore) and it's all free. My particular favorites from him are "my love still feels all wrong," "my love feels all wrong", and "semantic compositions on death and its meaning."
Also consider checking out these: "Breakcore Never Die," released by the Japanese breakcore label Tsugihagi Records, "アーメンマン vs メカアーメンマン," released by otherman records (another very nice Japanese breakcore label), Kei Toriki's Childhood Memories E.P. (also released by Otherman Records), YabaiKore! (released by Ragga Terror Front), and AMEN FREAKS Vol.1 (also released by Tsugihagi Records).
If you want some non-weeb, regular stuff, check out au2pilot's album "Stones."
