Country-outlaw icon Willie Nelson seems to have a cannabis-addled grin plastered on his dusty mug most of the time, but that doesnt mean he doesnt sing the blues. For this crossover celebration of feelin bad, Willie rounds up a juke joints worth of blues all-stars for assistance, including B.B. King, Jonny Lang, and Keb Mo. Together they remind us that the slow groove of The Thrill Is Gone and the boogie-woogie piano of Kansas City are timeless and can only gain a cool new dimension from Willies idiosyncratic warble. A country legend doing a whole album of blues might seem strange, but the end result will put a tear in your beer all the same.
