You may have to wait another six weeks to see Juliette Lewis on the big screen in the Drew Barrymore roller-derby flick Whip It!, but you can still catch the actress/singer/fashion maverick on the road right now with the Pretenders and Cat Power.

And you, special Music Mixer, can also get a sneak peak at a bluesy, sprawling track from her upcoming third full-length (the first without backing band the Licks), Terra Icognita, produced by the Mars Volta’s Omar Rodriguez-Lopez and due in stores September 1. Stream “Uh Huh” below:

var flashvars = {soundPath:”″, autoplay:”no”};

var params = {};

var attributes = {};

swfobject.embedSWF(“”, “singleflashPlayer”, “192”, “67”, “9.0.0”, “#FFFFFF”, flashvars);

What’s your take, readers — do you like Julia best on celluloid or in rock-girl mode? What do you think of her Licks-less new sound?
