Few venues can boast as impressive a second act as The Nile Theater, in downtown Mesa. Since reopening under the direction of Mantooth Group in 2010, the venue has spearheaded a kind of downtown revival, hosting punk and hardcore in the sweaty and utterly rock 'n' roll basement (re-dubbed The Underground as opposed to just "the Nile Basement") and singer/songwriter/indie fare in the neighboring (and couch-equipped) Lo-Fi Coffee. Punk and hardcore legends — like The Bouncing Souls and Alkaline Trio — take the stage, and the folks at Mantooth are never shy about fostering a DIY sense of community, tapping the best of the all-ages rock scene to open up for venerated lifers and play the annual Within These Walls festival. Downtown Mesa still has a way to go, but with the likes of the Nile Theater leading the way, it's easy to see things heading where they ought.
