Which artists' music do you buy without audition

I will second Richard Thomopson. I would also like to add James McMurphy and Steave Earle.

Son Volt
Jay Farrar
Califone
Monahans
Richmond Fontaine
Steven R. Smith
Wilco
J. Tillman

Never auditioned an artist or album in my life.

I find it funny that Steely Dan is listed so many times here. Like they release albums so often that you would need to listen to 'em first to make sure they didn't release a dirt-rock album ala Nickelback or something.
Jaybo...you've never EVER just listened to a cd in the store or previewed an album online before you bought it? How in the hell do you discover new music? Do you walk around the record store and just blindly buy albums with the shiniest covers?

Never intentially. I guess if hearing a single or a track on the radio, then I have. I would catagorize that as discovering. I've never had to hear a long player before purchasing though, and yes shiny covers have influenced blind buys my whole life.
