Echostream performs at @JapanSociety's "Concert for JAPAN" (pic set 9 of many)

Echostream is a real great, angsty rock band and they did an awesome set during the CfJ.  I highly recommend you check out their clips on YouTube ( http://youtube.com/echostream ) or their website: http://echostreammusic.com (they have more content on their YouTube, however).
