Truly great pop songs do not require a cheery outlook in order to work, nor do they pander to expectations of syrupy-sweet easy-listening. Rather, the best pop music is a matter of refinement and pure intention, of dialing groove to melody so that the two might puncture the malaise of everyday living in unison, revealing some brief, sober truth about our shared human condition. On their third full-length, "Moments Of Clarity," Narrow Head has achieved precisely this feat.
