Prog-rock pioneers King Crimson will not be playing their signature album In The Court Of The Crimson King on their upcoming U.S. tour - and guitarist Robert Fripp is urging fans expecting to hear it to sell their seats for a profit.

The legendary supergroup is making a live comeback in September (14) with a 17-date trek around the States, the band's first U.S. gigs since 2008.

However, band leader Fripp is warning fans not to attend the shows if they have a set idea of what tracks they want to hear the band play, as they will be in for a disappointing evening.

He tells Uncut magazine, "A guiding King Crimson principle is the music is new whenever it was written. So it's all new music. What I will say is, if you are coming with the explicit or implicit demand that you need to hear this music or that then don't come. And if you've already bought tickets, sell them to someone and you might make a profit.

"The point is with Crimson, if you come with an open mind, generally something worthwhile happens. If you don't, it's less likely. If you go there thinking, 'If I don't hear In the Court of the Crimson King I will have a lousy show', then you will have a lousy show. It's not on the setlist."
