Is Kanye West avoiding any domestic US concerts?

Kanye West has backed out of what would have been his first concert on U.S. soil since the unexpected death of his mother, Dr. Donda West, last month. The Minneapolis Star Tribune reports that West dropped off the bill for the KDWB Jingle Ball at the Target Center slated for Friday night (December 7) in Minneapolis with only a few days' notice, due to an unspecified "family matter." He's been on several concerts abroad now but cannot deal with one at home right now I guess. It's hard dealing with losing your mom especially during the holidays........
