What do these groups/ artists have in common besides legendary lyrical prowess?

They will all be on tour this summer with the ROCK THE BELLS TOUR!

Also appearing will be:

Immortal Technique
Raekwon, NAS, Dead Prez, Method Man, Red Man, Pharcyde,
Rakim, and many others. And yep not a female in the bunch. Not a one.

I am willing to brave just about anything including August Miami heat to see Tribe and Dela on the same stage. It's an old school dream come true!
