Throbbing Gristle. Now, that would be a great name for a rock band...oh wait, it is the name of a rock band. And that band — one of the premier industrial groups in the world — is coming to Chicago on April 25. At a church, no less. Tickets for the show at Epiphany (201 S. Ashland) are on sale now on Ticketweb, according to the Reader. There will actually be two separate shows; the first will be a live soundtrack to the 1980 film "In the Shadow of the Sun," while the second will be a proper set spanning the band's career.
