Immortal technique is one of the best mcs in his time, his lyrics are good, he energy he gives is amazing, he can rip up tracks, spit over any beats. I like the fact that he can switch and rip a track up like dominent species then talk about other issues like the bush, iraq, 'the cause of death' but like somebody else said they should not use tech as a history book, but he is saying to ppl go and read it for your self, go and read this book, etc
Back on track though, I dont think theres a problem that ppl read too much into songs, it shows that the artist is keeping them suprised and making their music curious.
