Brace yourself for a contingent of volatile duos at PhilaMOCA tonight: Trophy Wife’s show is one of five record release concerts for their latest album Sing What Scares You (out on 307 Knox Records and the band’s imprint Meet Your Adversary Records). Their sound incorporates reverb-y noise rock, grungy metal and pitched emotional battles between Diane Foglizzo and Katy Otto into riot grrrl synergy. Evoking nineties alt and post-hardcore as much as the current crop of Relapse Records bands (I’m looking at you, Royal Thunder), the female duo has built their reputation on their shows’ intense stage interactions and lyrical clarity. They’re joined this evening by two other duos, the also female-fronted Lozen of Seattle, the effects-heavy Erode and Disappear, and the unknown quantity Xanax (the latter two are from Philly).
