Byron,
If you didn't know,
We Talk about the Gabriel era Genesis (1967-1975) which produced Pieces Like Supper's Ready, Fountian of Salamacis, Dancing With the Moonlit Knight, The Musical Box, The Cinema Show, Firth of Fifth, In the cage etc.
and NOT the Phil collins Lead "Jesus He Knows Me" Genesis from the Late 80's and early 90's.
as for the 1976-1983 period, It's Subjective to the fan.
Most REAL genesis Fans like it UP to 1977. But can enjoy some material up to 1981/3 as well.

BTW, After Phil Left Genesis In 1996, they recruited a young Scottish Singer named Ray wilson and a young Israeli Drummer named Nir Zidkiyahu and released the album "Calling All Stations".
