Pigeonhole Carrie Rodriguez at your peril. Sure, she's done a lot of duets. She plays a fiddle. (a mean one at that.) She's recorded songs with a pleasing, folksy twang. But don't think you know what you're getting. Not yet 30, and with a critically-acclaimed solo record and several well-received duet records in her wake, the classically trained singer/songwriter has just begun flexing her artistic muscles, still figuring out how far her talents will take her. If you're looking for someone playing it safe and sticking to tried-and-true ways of music making, as the title of Rodriguez's daring new album aptly states, She Ain't Me.
