June 13 Dale Earnhardt Jr. Jr. w/ EMA The Waiting Room Lounge, 6212 Maple St. $10, 9 p.m., onepercentproductions.com Buckle up for this one. Detroit songwriting duo Josh Epstein and Daniel Zott have catapulted themselves to a Warner Brothers record deal for their just-released album It’s A Corporate World, thanks to a pop-centered take on skittering indie electronica grab-baggery. Live, the two don NASCAR jackets and crib from 70’s yacht-pop, 80’s synth pop and more. Opener EMA, the initials of Erika M. Anderson, garnered her own praise, after stepping out from her overlooked group Gowns. Her new album, Past Life Martyred Saints, is a claustrophobic ride through her personal turmoil, sounding like an art-damaged young Liz Phair, if the pain and heartbreak leaked out in spurts of bedroom indie electronic pop instead of over guitar-strumming ruminations.
