If there's a better combo than music and nachos, we don't know it. (Ed. note: how about music, nachos, and beer?) Nachos NY feeds that need literally this evening at its combo CMJ showcase and pig-out fest — today just so happens to be the International Day of the Nacho, if you weren't aware. While you're chowin' down, three bands take turns serenading you. We're longtime fans of ARMS, now a full band led by former Harlem Shaker Todd Goldstein; he's joined by LA-based indie-poppers Graydon (responsible for the official Nachos NY theme song) and Cuban-influenced instrumentalists Afuche.
