Thursday, Sept. 12 at the Astro in La Vista was an all-star affair, including the folks behind the scenes. “You notice your ears aren’t ringing?” location sound recordist Jeremy Wade Rodman, this reviewer’s plus-one to the event said at the end of the night. “That’s because the band’s sound guys know exactly how to tune the amps so that you hear every note, but it isn’t so loud that it kills your hearing. I suspect the artists’ sound guys are the best of the best.”
