"I write my life as it progresses, as it gets worse whatever," says Aaron Yates, who headlines Friday at the Marquee Theatre under his nom de plume, Tech N9ne (Blaze Ya Dead Homie opens the show). "I'm like a fan inside this cat called Tech N9ne who writes this crazy stuff. I'm just waiting to see what the beats are going to bring out of me, and this time, it brought out a masterpiece." That's Tech N9ne's modest assessment of his latest disc, Everready and if others are unlikely to place it among the pantheon of all-time-great hip-hop platters, they're apt to enjoy its variety. Tech N9ne divides his personality into three characters the King, the G, and the Clown with music to match. Moreover, he's one of the few hip-hoppers to have developed a reputation as a strong live artist. "I used to be a dancer, so we've got choreographed moves and everything," he points out. "It's not just grabbing your crotch and walking back and forth." No wonder Tech N9ne is a triple threat.
