A lot of people would say no, not since Fish left, but I wonder.
Marillion's music has certainly gone in another direction since the Big Yin (sorry!) departed for a solo career, and much of their music is more mainstream-acceptable now, but I still think their last few albums have had some very prog-worthy tracks on them, for instance "Interior Lulu" from Marillion.com, "A few words for the dead" from Radiation, "Neverland" from Marbles and perhaps even "The last century for Man" from the newest, Somewhere Else.
Any comments?
