Best Rock Albums in 2009, so far

As a few others have mentioned, Dan Auerbach "Keep It Hid" is excellent.

I will add the following recommendations that I did not catch above.

Patterson Hood "Murdering Oscar"
Black Joe Lewis & the Honeybears "Tell 'Em What Your Name Is!"
Deer Tick "Born on Flag Day"
Jason Isbell & the 400 Unit self-titled
Mastodon "Crack the Skye" (if you dig metal)

Try Booker T - Neil Young & Drive By Truckers : Potato Hole . Every track is good and the sound is awesome (not compressed like Dave Mathews recent effort) - this is one that can go into heavy rotation.

Shandorne: excellent golf shot. Great album!!!

Yeah Booker's album also rocks with the best of 'em.

I saw Booker back Neil Young in Europe, Summer 1993, with the entire MGs as the backup band. Booker loved the feel of those dates and tried to recreate this with Potato Hole. Neil returned a favor by contributing with this album. The shows are legendary in live touring circles. I caught five of the shows. Better than any shows I have seen with the Stray Gators and Crazy Horse. Always closed with a firery rendition of "All Along The Watchtower." Absolutely one of the tightest bands ever. There is an excellent article/interview with Booker in Wax Poetics Magazine you should track down that details this.
