I was a particularly anxsty teenager at the time, but I do remember there being plenty of hype and speculation about "LP7" in Radiohead fan circles before In Rainbows finally arrived.

If I recall it was initially a self released pay how much you want download.

I believe this was a 'first' and there was more hype about that than the album itself.

In Rainbows is my favorite Radiohead album for sure, closely followed by the Bends.

I do remember the "name your price" thing, but it seems I've completely forgotten it was unannounced release!

Therefore, there was virtually no hype...
