All Junglists look out, top ranking MC Top Cat is at Yugong Yishan this Sunday night. Coming straight outta' Manchester, Top Cat had a string of hits like "Champion DJ" and "Original Ses [Police in Helicopter]." If you're unfamiliar with ragga jungle, it's hyped up dancehall MCing over breakbeats. Rawer than drum and bass, and damn good when it's done well. Here's a solid introduction to the genre.
Aside from appearing on a ton of classic tracks in the 90s and early aughts, Top Cat wrote a book entitled "How To MC" and gives seminars around the world on this topic. More info here.
