Steven Wilson's solo album Insurgentes is truly brilliant, a stunning record that allows him to stretch the envelope a bit more than he can do in PT.
I started listening to the newer era PT first and worked my way backward, I actually love it all.
I've also been on a kick with bands like Opeth, Mastodon, Pelican, Yob, Shrinebuilder, etc.
LOTS of really good progressive/heavy music out there these days.
