I think so, don't know for sure if he did their main album in particular, but seems to be that way, yes.
I woulden't be surprised, it's a good album. I didn't like it much except a song or 2, at first - Then it's uniqueness grew on me.
wikipedia states that a certain kevin augunas produced robbers and cowards, along with the band themselves.
although, on an interesting note, matt wignal of havalina fame engineered on two songs and provided the photography. if you look around, his pics are on a ton of different albums. also: matt maust, whom i believe performed with havalina for awhile, is cwk's bassist.
off-topic, i know.

Aren't they kinda blusey?
that's one way to put it, yeah. bluesy but darn good. they came outta nowhere for me, took me a few listens to get used to.
