*Yes, he wore a skirt at last week’s “12-12-12” Concert for Hurricane Sandy relief, but is that the reason Kanye West was the only musical performer not featured on the newly-released album of the event?  Even special guests Michael Stipe, Eddie Vedde rand comic Adam Sandler made the cut.

Billboard.com pointed out the slight in an article, and at press time had received no comment from reps for West, his label, or Clear Channel’s John Sykes (who co-produced the concert with Madison Square Garden CEO James Dolan and Weinstein Company co-chairman Harvey Weinstein). A rep for Columbia, which is distributing the album, said that the label was unable to comment on the track listing.

A different source told Billboard that West’s performance isn’t included because of a decision made by his own camp, but was not able to clarify whether that was for personal, legal or other reasons.

Two other sources speculated that given West’s perfectionism where his music is concerned, it’s likely that he wasn’t happy with the performance, which was not as enthusiastically received as sets from the classic rock acts. It’s possible that the format of West’s performance — a long 13-song medley with multiple samples — caused legal challenges that couldn’t be resolved in time to make the digital release date, but a publishing source said that probably was not the case, given the scale of the project.

“12-12-12 The Concert for Sandy Relief” was released digitally on Dec. 18 and is currently projected to sell between 125,000 and 150,000 units in its first week. The 2-CD physical version is scheduled for release next month.
