First things first. It's pronounced Juh-Jamz. Like you have a stutter.
JJAMZ. Why do we feel like we already know them? Is it because James is the lead guitarist for the always radio ready Maroon 5? Jason the drummer of indie institutions Rilo Kiley and Bright Eyes? Alex the singer/writer/guitarist from Phantom Planet and Mark Ronson's solo records? Michael a beloved musician/artist/designer? And Z the leader of LA girl gang The Like?
No? Not ringing any bells? Maybe it's because this is how you feel when you hear something...
