You're doing yourself a disservice if you haven't checked out CHVRCHES yet. They remind me a bit of Purity Ring (if you're into that kind of music) + BBC listed them as promising new music talent for 2013. I heard great things about there show in NYC a few weeks back which convinced me that I needed to see them this June at Lincoln Hall.
Ps. I wish so much that this concert was on a Sunday so that I could say I was going to "church."
