Screw the rumors of a holographic Tupac tour or boring 3D Katy Perry movies: This fall, Primus fans will get the ultimate concert-going experience. The funky band has announced a 3D-enhanced tour, “sure to provide a one-of-a-kind psychedelic experience” and featuring “Quad Surround Sound.” Details are still a little hazy as to what this tour will entail, but presumably, in this case, 3D means something beyond just being able to see the band members standing on the stage.
