About a decade ago multi-instrumentalist Ryan McPhun left California for Auckland, N.Z. He joined several groups before deciding to front his own, Ryan McPhun & the Ruby Suns. McPhun did a considerable amount of traveling—spending time in Africa and Asia before settling in New Zealand—so it’s no surprise that his band, now simply called the Ruby Suns, makes upbeat pop music with world-music (and psychedelic) influences. The Ruby Suns worked with Beach House and Grizzly Bear producer Chris Coady on their fourth LP, last month’s Christopher (stream it below). The album is filled with heavy hooks and big electro-pop sounds, and you can hear plenty of it when they play the late show tomorrow night at Mercury Lounge.
