“Stay./ We’re a garden fed from then blood/ Left in your veins /So stay with me or I’ll shrivel and dry out.” These daunting lyrics of Atlanta-based band O’Brothers’ song, “Ascension,” mirror the dark sound of its music.“O’Brother is one of those bands that define heavy. Not by modern standards but from the ‘90s. It’s in this middle ground where it is huge and epic. It’s brutalizing, but it’s beautiful. It has so much interesting characteristic to it. It has really blown up in the last couple of years because people are like, ‘Wow, people are making real music again.’ It’s not just recycled mismatch,” said Si Lewis, guitarist of local band, Amplifiers.O’Brother is bringing its ambient sound to Stage AE on Sept. 10 accompanied by Amplifiers and two other similar-sounding bands Native and Daylight.  Lewis describes O’Brothers “heavy” sound as a textural layering of their soundscapes. It is not the modern understanding of “heavy,” which is usually thought of as metal or hardcore, but similar “heavy” sounds like Nine Inch Nails and Alice In Chains.“They were heavy not because they tuned their guitars down to drop-nothing sub-octave and knew how to chug open strings, but because they were layered and textural and epic sounding.  If you saw any of them live it felt like you were being beaten against a solid wall of sound, and you loved every second of it, because there was no space left in the aural spectrum to fit anything else. It was just completely full,” Lewis said.O’Brother’s tour began in Birmingham, Ala. on Aug. 14, headed west to California, and is moving back east to Pittsburgh. The band had nothing but success on its current tour. Because of this success, there are high expectations for its upcoming Pittsburgh show.“It’s been awesome. It is our first headliner. We don’t know what to expect in each city, but people are coming out,” said Jordan McGhin, O’Brother’s guitarist and the youngest member of the band, in a phone interview on Thursday.“We played in Pittsburgh before with the Circa Survive tour, and it was awesome, so hopefully if it is anything like that it will be great.”Jeremy Olson, manager of The Club at Stage AE also expects a nice crowd and performance.“[Ticket sales] have been pretty good. We hope the local support brings in a good amount of people. I’m expecting great things,” said Olson in a phone interview Friday.A majority of the local support Olson is referring to can be credited to Amplifiers. Amplifiers has done an avid amount of marketing about the show to its fans and will be making an appearance in the lineup of opening bands for O’Brother.  Lewis has been promoting this show to his fans and is a fan of O’Brother’s music himself.“They are incredible live. They are probably one of the loudest and biggest sounding bands live. And when I say probably I mean definitely,” Lewis said in a phone interview Thursday evening.Along with the heavy sounds of O’Brother and Amplifiers;, opening bands include Indiana–based rock band, Native, and Doylestown, Pa. band, Daylight.“The lineup is great. Native is awesome. Daylight is awesome. They are on the up and coming , and somehow we managed to weasel our way in too,” Lewis said. To hear O’Brohter’s intense, weighty sound and experience them live, see them at Stage AE Tuesday, Sept. 10. Doors open at 6:30 pm.
