I'll have to give ...But Seriously a full listen.  I have a paid Google Music account.  The album must be available there.  I never really knew the details of the Genesis break-up/implosion/explosion...whatever it really was.  In fact, I really don't know anything about Genesis, I'm embarrassed to admit!
The mid-to-late 1960s thru 1980 is my favorite period of music.  Floyd is my favorite, but I have an extremely diverse taste in music.  I really should look into the history of Genesis.  The true Prog Rock bands - I kind of jumped over them.  I don't consider Floyd to be true Prog Rock.  Genesis, King Crimson, Yes, Emerson Lake & Palmer...those are true Progressive bands - it's in the musical structure.  It's funny, because I do like a lot of songs from those four bands I just mentioned, yet I never went out and bought a single album from any of them when I was a teenager.
Phil Collins, Mike Rutherford, Peter Gabriel and the keyboard dude.  All four of them masters at their craft.  And all four in one band...Jesus.  It's almost mind boggling that I would skip these bands.  I don't think Collins was with them in the beginning though.  What a talented bunch.  Why does that always cause the most discontent?
