I enjoy both of those bands as well.
There's a short but sweet live recording of an Explode Into Colors show, available at this site, in the format of your choice:

Hope you enjoy the Warpaint radio session. I'm also currently listening to Wild Flag's song "Glass Tambourine", and i'm enjoying it. Another all-girl band that i will surely pay attention to when they actually release some official artifacts...
