Morgan Phelps pounds out impossible Primus-style basslines on his fifteen-string Warr Guitar, and guitarist Tom McCain shreds like a machete. Singer Eric Nepodal actually sings in key during the ever-changing musical madness. What results is an esoteric sound that's often too technical for common listeners who don't wet themselves over odd time signatures. But die-hard prog-metal geeks do, and they'll be blown away by Unknowing.
