So it's not like they're playing video game songs -- in fact, many chip musicians would really prefer not to be associated with Super Mario nostalgia -- and yet for those of us who grew up playing games on that hardware, it's still oddly comforting (and sometimes mind-bending) to hear.
To be honest, while I've always appreciated chip music -- I interviewed Nullsleep for Paste Magazine last year -- I never really found it casually listenable. But getting to see it live, complete with visuals and virtuosos wailing on videogame machines inside a crush of other fans was really a pretty singular experience. My personal faves from the show, if I had to pick, were Bubblyfish and Glomag, but I hugely recommend checking out and supporting some of these artists if it sounds like your thing!
I took more photos, but holding up an iPhone in a dancing crowd when you're as short as I am, tottering on heels, and in the sauce is not so much a good method for capturing events. Thankfully, Giz and the NYT have coverage, and I'm sure plenty of other folks do too.
