Genesis, in its Peter Gabriel-fronted, "classic" iteration, was possibly the most creative, intellectually stimulating, and inspired band of the entire first wave of British progressive rock. There was the weight of albums that displayed the group's uncanny propensity for long-winded (yet never idle) sonic explorations and the perfectly wrought lyrical content that traveled deftly between epics of science fiction and gritty. Also, the colorfully rendered social commentary and the dynamic, visceral assault brought to the music by each of the band's five virtuosos. Early Genesis was an absolute force of nature who's legacy survives mythologically.
Guitarist Steve Hackett played no small role in developing the sound of those records. While Gabriel's dramatic voice and performances and Phil Collins' percussive prowess seem to be at the center of most Genesis discussions, Hackett's flare for pioneering unique techniques (two-handed tapping, off-kilter effects) inarguably changed the way the guitar has been approached for decades while fueling the rock side of Genesis' prog.
