I'm sure most of these were already mentioned. But what the heck, right?
The Alive catalogue proved to be most enjoyable.
Left Lane Cruiser is most kinds awesome, attitude, simplicity, songs about food, come on, it's pretty hard not to love those guys.
Hacienda is another one. Great beatleasque sound and positive vibes.
Burnside and Kimbrough Despite being a dedicated blues scholar long before hearing TBK, I never had the opportunity (or interest, for that matter) to examine them in more detail. "Going Down South" cover and Chulahoma disc changed that.
Buffalo Killers great band, already mentioned, but I really had hard time getting into it, mostly because the lead singer's voice, perhaps unjustly, always happened to conjure the images of Axl Rose. I can't say I've completely got rid of that first impression.
Radio Moscow is a bit too derivative. But that Hendrix-like guitarwork is a fantastic marvel to behold.
