English super-group Genesis have lived a long musical journey in two parts, launching the careers of sophisticated solo artists Peter Gabriel and Phil Collins in the process. During the 1970's, Genesis helped define the genre of prog-rock. Progressive rock, as it came to be known, derived from the psychedelic 60's but took the sound to sprawling new highs. Genre hallmarks included lengthy songs, often containing nearly operatic sections set off by complex changes in tempo and mood and, lyrically, songs tend to deal with mystical and drug-related themes. Also, prog bands were known to employ innovative studio techniques to create new sonic environments. Genesis formed in the late 60's, when vocalist Peter Gabriel met up with keyboardist Tony Banks while attending school in Surrey, England. They recorded their first album, From Genesis to Revolution, in 1969 after being spotted by local scenester Jonathan King. The debut disc hardly made a ripple commercially but the band felt like they had a good thing and decided to stick it out. They developed their hypnotic rhythm section and Gabriel's haunting melodies through extensive live gigging and their 1970 record Trespass provoked interest with it's seven minute long Ghandi-inspired cut "The Knife." By 1973 their live show had evolved into an intense theatrical spectacle-they pioneered the use of arena lasers-and their album Selling England By the Pound was a hit with critics, tackling Gabriel's leftist politics and guitarist Steve Hacket's unprecedented new solo techniques on songs like "I Know What I Like (In Your Wardrobe)" and "Firth of Fifth." Genesis' most ambitious record would have to be their 1974 follow-up, The Lamb Lies Down On Broadway, a concept record that chronicled the adventures of a Puerto Rican-American youth lost in a parallel New York City.
