When I first started listening to Porcupine Tree 4/5 years ago, they were very obscure and I had such difficulties finding someone who ever heard of the, let alone fans.
Now I've noticed a much bigger increase in the number of people mentioning them.
Anyone else notice or recently discovered PT?
according the number of responses to this question.... guess not....

First time I heard of them was when you mentioned them in a question like three months ago. They are pretty good, and remind me of Pink Floyd-my favorite band

lol
yes there was an article about them in the Daily News...I was like WHAT?!?!? and it wasnt even a concert review, it was saying how everyone should go see them tonight (which i will!) my favorite & free music magazine The Aquarian loves Tree, and also had an article pushing tonights show, plus having their new record-ish album of the week, but then again, anything they put out gets straight to that spot. also WSOU radio loves Steven Wilson, plays and talks about him all the time. so really i tend to forget that they are underground/obscure cause they are everywhere i look =]

opeth helped a lot too
