Count me in as a Mosquitos fan, so I am also intrigued.  

I found the following on their website:
http://www.mosquitosnyc.com/news.php
<< What is going on?? What IS going on? WHAT is going on? Hard to say. We're recording, sometimes. Mosquitos' sister band... (er, 2nd cousin? not really sure of the correct relationship analogy) AM60 is featured in Old Navy's springtime campaign. Perhaps you've recognized Chris Root's vocals on Summertime Girlfriend? Maybe not. We're still here. Not much else to report.>>
