Dimebag Darrell's clean guitar solo at the end of Floods is widely considered the most emotionally devastating moment in heavy metal guitar history. After eight minutes of brutal groove metal, the song dissolves into a gentle, clean-toned solo of extraordinary beauty and sadness. Dimebag achieves more emotional impact in two minutes of quiet playing than most guitarists manage in an entire career of aggression.
