Hey Guys

I'm trying to sharpen up on my Blues Rhythm Chops at the moment, but find that on a lot of blues recordings there is very little rhythm guitar...a lot of the time being very basic or even left up to the bass and drums.

So I thought I'd throw it out to you guys for opinions. I'm primarly looking for slow/shuffel blues rhythms but I'll take a look at anything you think would be useful. I'm not looking for lessons, but more suggested listening, etc.
