Here's some basic suggestions that are only really scratching the surface:

The upcoming Wilco album is going to be pretty good. I've listened to an early leak of it that a friend had and it was definitely a different sound from their recent albums, and IMO, it sounds great. Different songs are evocative of the Beatles, The Band, Allman Brothers, and the Grateful Dead. I know that's a lot of name dropping, but you can hear those elements when you listen to it.

As for something old school, I would definitely recommend the Duane Allman solo anthology. It consists of a few Allman Brother songs, but mostly his collaborations with other musicians. Great stuff. My favorite is Mean Old World with Clapton. Of course, there's also Derek and the Dominos Live at the Filmore, and if you get the right version, you can also get the studio jams, which are mind blowing.

Bert Jansch's Black Swan was a great record released a year or two ago. He's been around for a long time. Check out the song Texas Cowboy Blues.

Also, if you dig Grateful Dead, make sure to get Dick's Picks volume 18. My favorite Dead concert of all time.

Hopefully you already have some of The Stooge s if you like early punk, but I thought I'd mention them just in case.

As for jazz, I agree with everything in gblowfish's post, and would only add Cab Calloway, Charles Mingus, and Grant Green.

I like the new Arcade Fire album, and would definitely recommend their earlier album Funeral.

The new Modest Mouse album is also pretty good, even if you don't like their earlier stuff.

EDIT: I forgot, I've got to add some love for Tropicalia music. Very influential stuff. I would recommend checking out Os Mutantes, Caetano Veloso, Jorge Ben, Gilberto Gil, etc.
