Wu-Tang Clan Misses Dates With Rage

September 2 [16:00 EDT] -- A bump in the road or the end of the road?

That's the question facing the Wu-Tang Clan/Rage Against The Machine tour after Wu-Tang failed to show for dates this weekend in Kansas City and St. Louis.

A Wu-Tang management spokesperson told MTV News on Tuesday that the group had taken itself off the bill in advance of Monday's Kansas City show so that they could perform at the third annual Park Hill Day in their native Staten Island. However, box office officials at Kansas City's Sandstone Amphitheater claim the cancellation was a surprise to them.

As for Saturday's missed show in St. Louis, management had no explanation.

Both venues offered full refunds until showtime, with some 800 Kansas City fans taking them up on the offer.

The Wu-Tang Clan was scheduled to play Minneapolis on Wednesday, but a label source says they will cancel that show as well, so that they can come to New York to serve as presenters on Thursday night's

MTV Video Music Awards show.

Label sources insist that the Clan will return to the road Friday in Dallas.
