The final acts have just been announced for next months' 25th anniversary Hardly Strictly Bluegrass Festival, with Wilco vocalist Jeff Tweedy added to a lineup that already included String Cheese Incident, Reverend Horton Heat, and Dengue Fever. It was pretty obvious as early as May of this year who a pretty large chunk of the artists playing would be at this year's 25th annual Hardly Strictly Bluegrass Festival (October 3-5), when they announced a night-before-the-festival Emmylou Harris tribune concert at The Masonic.
