Phil Collins is a mug that managed to ruin one of the best prog rock bands into a shitty one
You can say that again!!!
Okay then, just to make up for that poor (well, ehm, not THAT poor) band, here a few nominations:
Genesis - Watcher of the Skies
Genesis - First of Fifth
Genesis - the Musical Box
Genesis - The Cage
Genesis - The Fountain of Salmacis...
(all with Mr. Collins at the position where he should've stayed: behind the drumkit!)
And some current ones:
Porcupine Tree - Even Less
Anathema - One Last Goodbye
Oceansize - Frames
Pure Reason Revolution - The Million Ambassadors of Morning
