Tuesday, May 11 Cattle Decapitation has been on the road for months now; how tight do you think its live show has become? Once again, Cattle Decapitation is playing at Pop's (1403 Mississippi Avenue, Sauget, Illinois; 618-274-6720) as the opening band on a four-group slate, and once again, it will behoove you to get across the river early enough to catch the act. The virulently anti-meat avengers play ferocious grind with the conviction of a young Carcass, and even if you regularly partake of the sins of flesh (Mr. Night is devouring a gyro even as he types), you can't understand most of their lyrics anyway, as Travis Ryan's vocals are completely obliterated by the endless waves of distortion and blast-beats. But that's why they make lyric sheets, and besides, no one ever bangs his head to the lyrics. Tickets are $15 to $18; the show begins at 7:30 p.m.
