A bit! Possibly more than usual, actually - I've not got much money, so I've tended, predominantly, to absorb stuff that's outside progressive rock. I'll magpie my way through life - hear a cool bit of music on the telly, or at a party, or as an intro tape, and I'm becoming a little more mainstream if anything. This is my latest squeeze -

I think the core of the most popular bands remains the same because the thing that unites everyone here is that we're all fans of Dream Theater, or once were. That makes other biggish prog bands like Rush and Devin Townsend and Porcupine Tree a common ground that more of us share, and therefore the conversations can be bigger, stretch on longer. Just like a Doctor Who board would probably have a fairly active Torchwood thread, and a Merlin thread, and a Sherlock thread. Doesn't mean they're all anyone watches or listens to, just that they're the
only things
every-one watches.
