Dierks Bentley sure knows how to throw a party! Two nights prior to Sunday's Grammy Awards, Dierks performed at a Hollywood nightclub, The Knitting Factory, for an audience of industry folks, contest winners and a few lucky members of the public. During the concert, Dierks welcomed Miranda Lambert to the stage for a duet version of "Are You Sure Hank Done It This Way." Then, Brad Paisley made his entrance to cheers from the crowd. He and Dierks proceeded to tear into "Folsom Prison Blues" and the Buck Owens classic, "Act Naturally." Later in the set, which included plenty of hits and previews of a few new songs, Bentley invited Pearl Jam guitarist Mike McCready to join him in performing a couple of tunes. Dwight Yoakam also made an appearance on stage. Finally, in recognition of Dierks' four Grammy nominations, his fan club presented him a "gold record award." Bentley reacted, "I don't usually have a place for music awards in my house, but I'm making an exception for this one."
