London's Big Dada has been a lead soothsayer of the new hip-hop century, a role illustrated by the pan-global visions of this anniversary collection. It's all here: the early support of idiosyncratically English rappers like Roots Manuva and 2-step singers like Ty; the championing of American undie-gardes such as Busdriver and Infesticons; the hipster-mash, post-rap styles of French electro linguists TTC, sexed-up clubber Spank Rock and the worldly-wise DJ Diplo; and summarized by the Xxxchange remix of grime patriarch Wiley's "My Mistakes," where accented rhymes power a breaks-heavy groove. Not hip-hop, but of it.
