Unspecified health reasons cited as cause.

Days before it was set to begin, Cat Power's spring U.S. tour has been canceled due to unspecified health reasons. The 11-date trek, which was to feature Cat Power's Chan Marshall backed by the Memphis Rhythm Band, was set to begin Saturday (Feb. 11) in Memphis and continue through a high-profile March 15 gig in Austin, Texas, as part of the South by Southwest festival.

Marshall's new Matador album, "The Greatest," earned her the best sales week and Billboard 200 chart position of her career, debuting last week at No. 34 thanks to sales of 23,000 copies in the United States, according to Nielsen SoundScan. A Cat Power album has never been higher than No. 105 on the chart.

Matador has not released any additional information about the need for the cancellation "out of respect for Chan's privacy," but says the tour will be rescheduled as soon as possible. Refund information is still being nailed down.

"The Greatest" was recorded in Memphis with a host of notable session musicians, including guitarist Mabon "Teenie" Hodges, bassists Leroy Hodges and David Smith, guitarist Doug Easley, keyboardist Rick Steff, saxophonist Jim Spake and trumpeter Scott Thompson.
