The Doubleclicks are a nerd/folk/sister band who sing about Dungeons and Dragons, beatboxing, and lots and lots of heartbreak.
They post music quite frequently on the YouTubes. A song they wrote about Dungeons and Dragons has a rad animated music video.

They are based in Portland, Oregon. They’ve performed with Marian Call and in a “Nerds and Music” show with Paul and Storm, Hank Green and Mike Phirman. They sang backup for Paul & Storm at PAX once. It was awesome.
