I was turned on to them last year by this guy -
http://www.cannonz.com/originals.htm - a drummer from our small musical community... lol. Check him out, pretty talented dude. (not a promotional plug, just a point of interest, and Porcupine tree reminded me) I have Dark Wing and the song, Shallow is one of my favorite grooves and riffs ever. The song Open Car stands out to me as well. I like em alot, sometimes their a bit too ambient or mellow for me but I still like the stuff. About a month ago we got together and jamed, afterword he played some of their other stuff for me and made the point for me to listen to the drummer, let me tell you that guy really puts alot of sublte stuff into the music. This is definantly pne of the many bands on my catch up list.
